7.28 CMPLX — Complex conversion function

Description:

CMPLX(X,[Y,KIND]) returns a complex number where X is converted to the real component. If Y is present it is converted to the imaginary component. If Y is not present then the imaginary component is set to 0.0. If X is complex then Y must not be present.

Option:

f95, gnu

Class:

elemental function

Syntax:

C = CMPLX(X) C = CMPLX(X,Y) C = CMPLX(X,Y,KIND)

Arguments:

X	The type may be INTEGER(*) or REAL(*) or COMPLEX(*).
Y	Optional, allowed if X is not COMPLEX(*). May be INTEGER(*) or REAL(*).
KIND	Optional scaler integer initialization expression.

Return value:

The return value is of type COMPLEX(*)

Example:

          program test_cmplx
              integer :: i = 42
              real :: x = 3.14
              complex :: z
              z = cmplx(i, x)
              print *, z, cmplx(x)
          end program test_cmplx
