Overview
The IsNaN function tests a value as being an invalid float value. Infinite (+/-) counts as as a number.
Syntax/Parameters
Syntax
boolean = IsNaN ( float x );
Parameters
x
A float containing a numeric source value. If x is not a float, the data will be converted to a 64-bit floating-point number.
Return Value
Returns TRUE if x is not a number (NaN) or FALSE if it is a valid floating-point number.
Remarks
Note that the action of comparing two NaN values will fail since NaN is not considered a floating-point value.
