casin, casinf, casinl

Retrieves the arcsine of a complex number, with branch cuts outside the interval [-1, +1] along the real axis.

Syntax

_Dcomplex casin(
   _Dcomplex z
);
_Fcomplex casin(
   _Fcomplex z
);  // C++ only
_Lcomplex casin(
   _Lcomplex z
);  // C++ only
_Fcomplex casinf(
   _Fcomplex z
);
_Lcomplex casinl(
   _Lcomplex z
);

Parameters

z
A complex number that represents an angle, in radians.

Return value

The arcsine of z, in radians. The result is unbounded along the imaginary axis, and in the interval [-π/2, +π/2] along the real axis.

Remarks

Because C++ allows overloading, you can call overloads of casin that take and return _Fcomplex and _Lcomplex values. In a C program, casin always takes and returns a _Dcomplex value.

Requirements

Routine	C header	C++ header
casin, casinf, casinl	<complex.h>	<ccomplex>
