Inquiry Module Intrinsic Function (Generic): Returns whether the processor supports IEEE base conversion rounding during formatted I/O.
USE, INTRINSIC :: IEEE_ARITHMETIC
result = IEEE_SUPPORT_IO ([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 base conversion rounding during formatted input and output for all real values; otherwise, false.
If x is specified, the result has the value true if the processor supports base conversion rounding during formatted input and output for real variables of the same kind type parameter as x; otherwise, false.
The base conversion rounding applies to modes IEEE_UP, IEEE_DOWN, IEEE_TO_ZERO, and IEEE_NEAREST.
IEEE_SUPPORT_IO ( ) has the value true if base conversion rounding is supported for all real types during formatted I/O.
