VBScript Math Functions
Functions for manipulating mathematics expression.
Sgn Functionlast updated 9/21/2017Create an integer to indicate the sign of a given number.
SyntaxSgn(number) ArgumentnumberRequired. Any valid numeric expressionReturnsReturns a Variant of Integer data subtype containing the sign of a given number. Return Values of Sgn function: Sgn return valuesDescription1Number greater than zero0Number equal to zero-1Number Less than zero. Special returns of Sgn function: numberreturn valueNullRun-time ErrorEmpty0""Run-time Error Remarks- The return value of Sgn function is determined by the sign of a given number only.
Requirement1 Abs Functionlast updated 9/16/2017Create an unsigned magnitude, or the absolute value of a given number.
SyntaxAbs(number) ArgumentnumberRequired. Any valid numeric expressionReturnsReturns a Variant of the same given number data subtype containing the unsigned magnitude, or the absolute value of a given number. Special returns of Sgn function: numberreturn valueNullNullEmpty0""Run-time Error Remarks- The absolute value of a number is the unsigned magnitude of a number.
- always returns a positive number including zero except for a Null expression.
- an uninitialized variable is a valid nurmeric expression, but an empty sting or a space character is not a valid numeric expression.
