Descripción¶
ComplexConstructor represents constructor of complex type. A complex literal constant is a complex constructor where each expression if a pair of initialisation expressions.
Tipos¶
Only accepts complex and real types. The imaginary part can be 0 or can have value.
Ejemplos¶
program complex
integer :: i = 42
real :: x = 3.14
complex :: z1, z2
z1 = cmplx(i, x)
print *, z1, cmplx(x, kind=8)
z2 = cmplx(z2, kind=8)
end program complex
