ABS()Return the absolute value of a numeric expression ------------------------------------------------------------------------------SyntaxABS(<nExp>) --> nPositiveArguments<nExp>is the numeric expression to be evaluated.ReturnsABS() returns a number representing the absolute value of its argument. The return value is a positive number or zero.DescriptionABS() is a numeric function that determines the magnitude of a numeric value independent of its sign. It lets you, for example, obtain the difference between two numbers as a positive value without knowing in advance which of the two is larger. As a formalism, ABS(x) is defined in terms of its argument, x, as follows: if x >= 0, ABS(x) returns x; otherwise, ABS(x) returns the negation of x.Examples.These examples show typical results from ABS(): nNum1 := 100 nNum2 := 150 ? nNum1 - nNum2 // Result: -50 ? ABS(nNum1 - nNum2) // Result: 50 ? ABS(nNum2 - nNum1) // Result: 50 ? ABS(-12) // Result: 12 ? ABS(0) // Result: 0FilesLibrary is CLIPPER.LIB.
