Syntax edit

positiveValue = abs( expr )

Description edit

The abs function returns the absolute value of the numeric expression expr.

The absolute value of a number is its distance from zero. Thus, the number 3 has an absolute value of 3, while the number -12.34 has an absolute value of 12.34. The absolute value of zero is zero.

Notes edit

The standard abs function can accept either an integer or a floating-point expr parameter.

FB provides also the usr abs routine which originally used to execute faster with 68K applications. This is no longer the case, but the function is still present in the language for backward compatibility.
