### 8.198 `MAXEXPONENT` — Maximum exponent of a real kind ¶

Synopsis:

  `RESULT = MAXEXPONENT(X)`

Description:

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

Class:

  Inquiry function

Arguments:

  X | Shall be of type `REAL`.

  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

Standard:
