set_exponent

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
