CMPLX (The GNU Fortran Compiler) (original) (raw)
8.62 CMPLX — Complex conversion function ¶
Synopsis:
RESULT = CMPLX(X [, Y [, KIND]])
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.
Class:
Elemental function
Arguments:
| X | The type may be INTEGER, REAL,COMPLEX or UNSIGNED. |
|---|---|
| Y | (Optional; only allowed if X is notCOMPLEX.) May be INTEGER, REAL or UNSIGNED. |
| KIND | (Optional) A scalar INTEGER constant expression indicating the kind parameter of the result. |
Return value:
The return value is of COMPLEX type, with a kind equal toKIND if it is specified. If KIND is not specified, the result is of the default COMPLEX kind, regardless of the kinds ofX and Y.
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
Standard:
Fortran 77 and later, extension for UNSIGNED (see Unsigned integers)
