csqrt |
Function (ROM Call 0x146) |
Complex square root.
csqrt calculates the square root w = sqrt(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 square root is defined by
sqrt(z) = sqrt(abs(z)) (cos(arg(z)/2) + i sin(arg(z)/2))
where abs(z) = sqrt(z_re^2+z_im^2) and arg(z) = atan2(z_im, z_re).
See sqrt, atan2,
sin and cos.
