casin |
Function (ROM Call 0x13B) |
Complex arc sine.
casin calculates the arc sine w = asin(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 arc sine is defined by
asin(z) = -i ln (i z + sqrt (1 - z^2))
where ln and sqrt are complex natural
logarithm and complex square root (see cln and
csqrt).
Uses: asin, fabs, is_inf, is_nan, pow, sqrt, _bcd_math
