aimag(x): Imaginary Part¶
Imaginary part of complex number.
Declaration¶
Sintaxe¶
retval = aimag(x)
elemental real(sp) function aimag(x)
elemental real(dp) function aimag(x)
Argumentos¶
x the input value must be of complex type.
Valores de retorno¶
The return value is imaginary part of type real and kind same as of x.
Descrição¶
aimag(x) returns the imaginary part of the input complex argument x.
For x complex input value, the result is calculated using mathematical formula:
\(x + iy\)
\(i\) the imaginary part is the result.
Tipos¶
Supported argument types are complex.
interface aimag
module procedure saimag, daimag
end interface
contains
elemental real(sp) function saimag(x)
complex(sp), intent(in) :: x
end function
elemental real(dp) function daimag(x)
complex(dp), intent(in) :: x
end function
Exemplos¶
program intrinsics_aimag
implicit none
print *, aimag(1.0, -3.0)
end program
Resultado:
-3.0
