function Abs(Number Numeric type):Numeric type;
Returns the absolute value of an integer.
Syntax:
value := Abs(value);
Example:
Let's say you have a variable i. The type of this variable is assigned as integer. The value of this variable can be given an integer value. Here we have given a negative value. Finally, abs function was used to get the absolute value.
var
i : Integer;
begin
i := -1235;
ShowMessage('Before: '+ IntToStr(i));
//The absolute value of i is taken and put back to i.
i:= Abs(i);
ShowMessage('After: '+IntToStr(i));
end;
