ABS (Absolute Value)
The ABS function returns the absolute value of a number.
Syntax
ABS ( number )
The following example illustrates use of the ABS function.
Const PI = 3.141592654
Public X, Xabs, count
BeginProg
  Scan (1,Sec,0,0)
    count+=1
   'X is the sine of angles at pi/8 intervals
    X = SIN(count*PI/8)
   'Xabs is the absolute value of X
    Xabs = ABS(X)
  NextScan
EndProg
Remarks
The number argument can be any valid numeric expression. The absolute value of a number is its unsigned magnitude. For example, ABS(-1) and ABS(1) both return 1.
