Generate and return .true.
if the input value is an IEEEcompliant positive infinity.
If the input value is a complex
number, then the output is .true.
if any of the two real or imaginary components or both are positive infinities.
 Parameters

[in]  x  : The input scalar or array of arbitrary rank of either

type
complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128), or

type
real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),
whose value will be tested for being positive infinity. 
 Returns
infPos
: The output scalar or array of the same shape as the input x
of type logical
of default kind LK whose value is .true.
if the input x
is a positive infinity, otherwise it is .false.
.
Possible calling interfaces ⛓
logical(LK) :: infPos
Generate and return .true. if the input value is an IEEEcompliant positive infinity.
This module contains procedures and generic interfaces for testing for exceptional cases at runtime.

 Note
 A very simple test of positive infinity of a variable
x
is the condition x > huge(x)
that is .true.
if x
is a positive infinity.

The procedures under this generic interface are equivalent to
.not. (ieee_is_negative(x) .or. ieee_is_finite(x))
from the ieee_arithmetic
intrinsic module to detect positive infinity.
This generic interface extends this function also to complex
numbers.
