double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);
The functions compute the complex arc hyperbolic sine of z, with branch cuts outside the interval [
+i] along the imaginary axis.
z - a complex number.
These functions return the complex arc hyperbolic sine value, in the range of a strip mathematically unbounded along the real axis and in the interval [
+iπ/2] along the imaginary axis.
No errors are defined.
