8.217 SET_EXPONENT — Set the exponent of the model

Description:
SET_EXPONENT(X, I) returns the real number whose fractional part is that that of X and whose exponent part is I.
Standard:
Fortran 95 and later
Class:
Elemental function
Syntax:
RESULT = SET_EXPONENT(X, I)
Arguments:

X Shall be of type REAL.
I Shall be of type INTEGER.

Return value:
The return value is of the same type and kind as X. The real number whose fractional part is that that of X and whose exponent part if I is returned; it is FRACTION(X) * RADIX(X)**I.
Example:
          PROGRAM test_setexp
            REAL :: x = 178.1387e-4
            INTEGER :: i = 17
            PRINT *, SET_EXPONENT(x, i), FRACTION(x) * RADIX(x)**i
          END PROGRAM
