9.240 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
