USE, INTRINSIC :: IEEE_ARITHMETIC
result = IEEE_SUPPORT_STANDARD ([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. The result has the value true if the results of all the following functions are true (x can be omitted):
IEEE_SUPPORT_DATATYPE([x]) |
IEEE_SUPPORT_DENORMAL([x]) |
IEEE_SUPPORT_DIVIDE([x]) |
IEEE_SUPPORT_FLAG(flag [, x])1 |
IEEE_SUPPORT_HALTING(flag)1 |
IEEE_SUPPORT_INF([x]) |
IEEE_SUPPORT_NAN([x]) |
IEEE_SUPPORT_ROUNDING(round_value [, x])2 |
IEEE_SUPPORT_SQRT([x]) |
1 "flag" must be a valid value 2 "round_value" must be a valid value |
Otherwise, the result has the value, false.
IEEE_SUPPORT_STANDARD () has the value false if both IEEE and non-IEEE real kinds are supported.
