### 8.166 `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
