cot(3M)

DESCRIPTION

These functions are available only for Integrity servers.

cot() returns the cotangent of x (x specified in radians).

cotf() is a float version of cot(); it takes a float argument and returns a float result.

cotl() is a long double version of cot(); it takes a long double argument and returns a long double result.

cotw() is an extended version of cot(); it takes an extended argument and returns an extended result.

cotq() is equivalent to cotl() on HP-UX systems.

USAGE

To use these functions, compile either with the default -Ae option or with the -Aa and the -D_HPUX_SOURCE options.

To use cotw() or cotq(), compile also with the -fpwidetypes option.

To use any of these functions, make sure your program includes <math.h>, and link in the math library by specifying -lm on the compiler or linker command line.

RETURN VALUE

cot(±0) returns ±INFINITY.

If x is ±INFINITY, cot() returns NaN and raises the invalid exception.

x is NaN, cot() returns NaN.

When it raises no other exception, whether cot() raises the inexact exception is unspecified.

ERRORS

No errors are defined.
