Val

Calculate numerical value of a string.
Declaration

Source position: system.fpd line 49

procedure Val(

const S: String;

var V;

var Code: Word

);
Description

Val converts the value represented in the string S to a numerical value, and
stores this value in the variable V, which can be of type Longint, Real and
Byte. If the conversion isn't succesfull, then the parameter Code contains the
index of the character in S which prevented the conversion. The string S is
allowed to contain spaces in the beginning. The string S can contain a number in
decimal, hexadecimal, binary or octal format, as described in the language
reference.
Errors

If the conversion doesn't succeed, the value of Code indicates the position
where the conversion went wrong.
