S2R

Parameters

s

string

The string to be converted.

comment

Returns a real by parsing the string for a number. Returns 0 for: values too big or too small, an empty string or text that doesn't start with a number.

Lua: For null raises an error.

note

This function only works for decimal strings. Hexadecimal or octal strings are not supported.

note

The parser stops at the first non-number character [0-9.] - does not support comma , as a decimal point. If the input string starts with some valid input but ends in invalid input this will return the conversion of the valid part: S2R(".123asd") == 0.123.

pure

This function is pure. For the same values passed to it, it will always return the same value.
