7.148 MAXEXPONENT — Maximum exponent of a real kind

Description:

MAXEXPONENT(X) returns the maximum exponent in the model of the type of X.

Standard:

Fortran 95 and later

Class:

Inquiry function

Syntax:

RESULT = MAXEXPONENT(X)

Arguments:

X	Shall be of type REAL.

Return value:

The return value is of type INTEGER and of the default integer kind.

Example:

          program exponents
            real(kind=4) :: x
            real(kind=8) :: y
          
            print *, minexponent(x), maxexponent(x)
            print *, minexponent(y), maxexponent(y)
          end program exponents
