If you want to get an integer value from a string, consider using ##[[KeyPgValint|ValInt]]## or ##[[KeyPgVallng|ValLng]]## instead.

If you want to convert a number into string format, use the ##[[KeyPgStr|Str]]## function.

Returns a converted ##[[KeyPgDouble Double]]## precision number
If the first character of the string is invalid, ##**Val**## will return ##0##.
##**Val**("10")## will return ##10.0##, and ##**Val**("10.10")## will return ##10.1##. The function parses the string from the left, skipping any white space, and returns the longest number it can read, stopping at the first non-suitable character it finds. Scientific notation is recognized, with ##"D"## or ##"E"## used to specify the exponent.
##**Val**## can be used to convert integer numbers in binary / octal / hexadecimal format, if they have the relevant identifier (##"&B"## / ##"&O"## / ##"&H"##) prefixed, for example: ##**Val**("&HFF")## returns ##255##.
If you want to get an integer value from a string, consider using ##[[KeyPgValint ValInt]]## or ##[[KeyPgVallng ValLng]]## instead. They are faster, since they don't use floating-point numbers, and only ##[[KeyPgVallng ValLng]]## provides full 64-bit precision for ##[[KeyPgLongint LongInt]]## types.
