Syntax
 
MINEXPONENT (x)
 

Arguments

x is an INTENT(IN) scalar or array of type REAL.

Result

The result is a scalar default INTEGER. Its value is the most negative binary exponent possible in the data type of x.

Example
       write(*,*) minexponent(1.e0) ! writes -125
       write(*,*) minexponent(1.d0) ! writes -1021
       write(*,*) minexponent(1.q0) ! writes -16381
