NaN()

Syntax

Result.f = NaN()

Returns the special floating-point value representing 'Not a Number'. This value is returned from invalid calculations such as calculating the square root of a negative number.

Parameters

None.

Return value

Returns the value representing NaN. The result is a float or double value depending on whether it is assigned to a float or double variable.

Remarks

NaN is a special value. Using NaN in any calculation with other values will again return the value NaN. The IsNaN() function can be used to check whether a variable represents the value NaN.

Example

  Debug IsNaN(NaN() * 5 + 2) ; will display 1
