abs - Function

Description

Returns the absolute (positive) value of an argument as an INT or FLOAT value depending on the type of the argument.

Syntax

  y:=abs(x);

  int/float y;
  int/float x;

Principal parameters

Optional parameters

None.

Return value

If x is an INT value, abs() returns an INT. If x is a FLOAT value, abs() returns a FLOAT.

Comments

The abs() function is different from other functions by its dual nature of being both an INT and a FLOAT function. This means that if i is an INT, the MBS compiler will accept i:=abs(55); but not i:=abs(55.7);
