| casinh | Function (ROM Call 0x13E)

math.h, timath.h

void casinh (float z_re, float z_im, float *w_re, float *w_im);

Complex hyperbolic area sine.

casinh calculates the hyperbolic area sine w = asinh(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 hyperbolic area sine is defined by
asinh(z) = ln (z + sqrt (z^2 + 1))
where ln and sqrt are complex natural logarithm and complex square root (see cln and csqrt).
