Intel® Fortran Compiler 17.0 Developer Guide and Reference
Inquiry Intrinsic Function (Generic): Returns the minimum exponent in the model representing the same type and kind parameters as the argument.
result = MINEXPONENT (x)
x |
(Input) must be of type real; it can be scalar or array valued. |
The result is a scalar of type default integer. The result has the value emin, as defined in Model for Real Data.
If X is of type REAL(4), MINEXPONENT (X) has the value -125.
The following shows another example:
REAL(8) r1 ! DOUBLE PRECISION REAL
INTEGER i
i = MINEXPONENT (r1) ! returns - 1021.
