Function (ROM Call 0x141) |
Complex sine.
csin calculates the sine w = sin(z) of the complex number which real and
imaginary parts are z_re and z_im, and stores real and
imaginary part of the result in floating point destinations pointed to by
w_re and w_im. The complex sine is defined by
sin(z) = (exp(i z) - exp(-i z)) / (2 i)
where exp is complex exponential function
(see cexp).
