Inquiry Module Intrinsic Function (Generic): Returns whether the processor supports IEEE denormalized numbers.
USE, INTRINSIC :: IEEE_ARITHMETIC
result = IEEE_SUPPORT_DENORMAL ([x])
x |
(Input; optional) Must be of type REAL; it can be scalar or array valued. |
The result is a scalar of type default logical. If x is omitted, the result has the value true if the processor supports arithmetic operations and assignments with denormalized numbers for all real values; otherwise, false.
If x is specified, the result has the value true if the processor supports arithmetic operations and assignments with denormalized numbers for real variables of the same kind type parameter as x; otherwise, false.
IEEE_SUPPORT_DENORMAL () has the value true if IEEE denormalized numbers are supported for all real types.
