f95, gnu

Class:

elemental function

Syntax:

X = DBLE(X) X = DFLOAT(X)

Arguments:

X	The type shall be INTEGER(*), REAL(*), or COMPLEX(*).

Return value:

The return value is of type double precision real.

Example:

          program test_dble
              real    :: x = 2.18
              integer :: i = 5
              complex :: z = (2.3,1.14)
              print *, dble(x), dble(i), dfloat(z)
          end program test_dble
