Inquiry Intrinsic Function (Generic): Returns the maximum exponent in the model representing the same type and kind parameters as the argument.
result = MAXEXPONENT (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 emax, as defined in Model for Real Data.
REAL(4) x
INTEGER i
i = MAXEXPONENT(x) ! returns 128.
