casin(3M) casin(3M) NAME
casin(), casinf(), casinl(), casinw(), casinq() - complex arcsine functions SYNOPSIS
DESCRIPTION
These functions are available only for Integrity servers. returns the complex arcsine of z, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [-Pi/2,+Pi/2] along the real axis. Branch cuts are outside the interval [-1,+1] along the real axis. is a version of it takes a argument and returns a result. is a version of it takes a argument and returns a result. is an version of it takes an argument and returns an result. is equivalent to on HP-UX systems. USAGE
To use these functions, compile with the default option. To use compile with the option. Make sure your program includes Link in the math library by specifying on the compiler or linker command line. RETURN VALUE
= and is an odd function. returns 0+i0. returns Pi/2+iInf for positive-signed finite y. returns NaN+iNaN and may raise the invalid exception for finite y. returns +0+iInf for positive-signed finite x. returns Pi/4+iInf. returns NaN+iInf. returns +0+iNaN. returns NaN+iNaN and may raise the invalid exception for finite nonzero x. (where the sign of the imaginary part of the result is unspecified). returns NaN+iNaN. ERRORS
No errors are defined. SEE ALSO
