		Built-in string class.
	</brief_description>
	<description>
		This is the built-in string class (and the one used by GDScript). It supports Unicode and provides all necessary means for string handling. Strings are reference-counted and use a copy-on-write approach, so passing them around is cheap in resources.

			<argument index="0" name="to" type="String" />
			<description>
				Performs a case-insensitive [i]natural order[/i] comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order. Internally, lowercase characters will be converted to uppercase during the comparison.
				When used for sorting, natural order comparison will order suites of numbers as expected by most people. If you sort the numbers from 1 to 10 using natural order, you will get [code][1, 2, 3, ...][/code] instead of [code][1, 10, 2, 3, ...][/code].
				[b]Behavior with different string lengths:[/b] Returns [code]1[/code] if the "base" string is longer than the [code]to[/code] string or [code]-1[/code] if the "base" string is shorter than the [code]to[/code] string. Keep in mind this length is determined by the number of Unicode codepoints, [i]not[/i] the actual visible characters.
				[b]Behavior with empty strings:[/b] Returns [code]-1[/code] if the "base" string is empty, [code]1[/code] if the [code]to[/code] string is empty or [code]0[/code] if both strings are empty.
				To get a boolean result from a string comparison, use the [code]==[/code] operator instead. See also [method nocasecmp_to] and [method casecmp_to].

		<method name="num" qualifiers="static">
			<return type="String" />
			<argument index="0" name="number" type="float" />
			<argument index="1" name="decimals" type="int" default="-1" />
			<description>
				Converts a [float] to a string representation of a decimal number.
				The number of decimal places can be specified with [code]decimals[/code]. If [code]decimals[/code] is [code]-1[/code] (default), decimal places will be automatically adjusted so that the string representation has 14 significant digits (counting both digits to the left and the right of the decimal point).
				Trailing zeros are not included in the string. The last digit will be rounded and not truncated.
				Some examples:
				[codeblock]
				String.num(3.141593)     # "3.141593"
				String.num(3.141593, 3)  # "3.142"
				String.num(3.14159300)   # "3.141593", no trailing zeros.
				# Last digit will be rounded up here, which reduces total digit count since
				# trailing zeros are removed:
				String.num(42.129999, 5) # "42.13"
				# If `decimals` is not specified, the total amount of significant digits is 14:
				String.num(-0.0000012345432123454321)     # "-0.00000123454321"
				String.num(-10000.0000012345432123454321) # "-10000.0000012345"

		<method name="rfindn" qualifiers="const">

		<method name="right" qualifiers="const">
			<return type="String" />
			<argument index="0" name="position" type="int" />
			<description>
				Returns a number of characters from the right of the string. If negative [code]position[/code] is used, the characters are counted downwards from [String]'s length.

				print("sample text".right(-3)) #prints "ple text"
				[/codeblock]

		<method name="rpad" qualifiers="const">
			<return type="String" />
			<argument index="0" name="min_length" type="int" />
			<argument index="1" name="character" type="String" default="&quot; &quot;" />

		<method name="rsplit" qualifiers="const">
			<return type="PackedStringArray" />
			<argument index="0" name="delimiter" type="String" />
			<argument index="1" name="allow_empty" type="bool" default="true" />
			<argument index="2" name="maxsplit" type="int" default="0" />
			<description>
				Splits the string by a [code]delimiter[/code] string and returns an array of the substrings, starting from right.
				The splits in the returned array are sorted in the same order as the original string, from left to right.
				If [code]maxsplit[/code] is specified, it defines the number of splits to do from the right up to [code]maxsplit[/code]. The default value of 0 means that all items are split, thus giving the same result as [method split].
				Example:
				[codeblocks]
				[gdscript]
				var some_string = "One,Two,Three,Four"
				var some_array = some_string.rsplit(",", true, 1)
				print(some_array.size()) # Prints 2
				print(some_array[0]) # Prints "Four"
				print(some_array[1]) # Prints "Three,Two,One"
				[/gdscript]
				[csharp]
				// There is no Rsplit.
				[/csharp]
				[/codeblocks]

				Returns a copy of the string with characters removed from the right. The [code]chars[/code] argument is a string specifying the set of characters to be removed.
				[b]Note:[/b] The [code]chars[/code] is not a suffix. See [method trim_suffix] method that will remove a single suffix string rather than a set of characters.

			<argument index="0" name="delimiter" type="String" />
			<argument index="1" name="allow_empty" type="bool" default="true" />
			<argument index="2" name="maxsplit" type="int" default="0" />
			<description>
				Splits the string by a [code]delimiter[/code] string and returns an array of the substrings. The [code]delimiter[/code] can be of any length.
				If [code]maxsplit[/code] is specified, it defines the number of splits to do from the left up to [code]maxsplit[/code]. The default value of [code]0[/code] means that all items are split.
				If you need only one element from the array at a specific index, [method get_slice] is a more performant option.
				Example:
				[codeblocks]
				[gdscript]
				var some_string = "One,Two,Three,Four"
				var some_array = some_string.split(",", true, 1)
				print(some_array.size()) # Prints 2
				print(some_array[0]) # Prints "Four"
				print(some_array[1]) # Prints "Three,Two,One"
				[/gdscript]
				[csharp]
				var someString = "One,Two,Three,Four";
				var someArray = someString.Split(",", true); // This is as close as it gets to Godots API.
				GD.Print(someArray[0]); // Prints "Four"
				GD.Print(someArray[1]); // Prints "Three,Two,One"
				[/csharp]
				[/codeblocks]
				If you need to split strings with more complex rules, use the [RegEx] class instead.

			<description>
				Converts the String (which is a character array) to ASCII/Latin-1 encoded [PackedByteArray] (which is an array of bytes). The conversion is faster compared to [method to_utf8_buffer], as this method assumes that all the characters in the String are ASCII/Latin-1 characters, unsupported characters are replaced with spaces.
			</description>
		</method>
		<method name="to_float" qualifiers="const">
			<return type="float" />
			<description>
				Converts a string containing a decimal number into a [code]float[/code]. The method will stop on the first non-number character except the first [code].[/code] (decimal point), and [code]e[/code] which is used for exponential.
				[codeblock]
				print("12.3".to_float()) # 12.3
				print("1.2.3".to_float()) # 1.2
				print("12ab3".to_float()) # 12

			</description>
		</method>
		<method name="to_int" qualifiers="const">
			<return type="int" />
			<description>
				Converts a string containing an integer number into an [code]int[/code]. The method will remove any non-number character and stop if it encounters a [code].[/code].
				[codeblock]
				print("123".to_int()) # 123
				print("a1b2c3".to_int()) # 123
				print("1.2.3".to_int()) # 1

		<method name="to_utf8_buffer" qualifiers="const">
			<return type="PackedByteArray" />
			<description>
				Converts the String (which is an array of characters) to UTF-8 encode [PackedByteArray] (which is an array of bytes). The conversion is a bit slower than [method to_ascii_buffer], but supports all UTF-8 characters. Therefore, you should prefer this function over [method to_ascii_buffer].
