Detailed Description

.true. if IEEE NaN.

Checks for IEEE NaN, i.e. Not-a-Number.
Wraps to functions of the intrinsic module ieee_arithmetic.

Example

Returns .false. in all but 1st element

vec1 = (/ nan, 2., 3., inf, 5., 6. /)
isnan = is_nan(vec1)

Parameters

[in]

real(sp/dp) :: a

Number to be evaluated.

Return values

logical :: is_nan

\( a = NaN \), logically true or false.
