tand(3M)tand(3M)NAMEtand(), tandf(), tandl(), tandw(), tandq() - tangent functions of an
argument specified in degrees
SYNOPSIS
HP Integrity Server Only
DESCRIPTION
returns the tangent of x (x specified in degrees).
On PA-RISC systems, may lose accuracy when x is far from zero.
is a version of it takes a argument and returns a result.
Integrity Server Only
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 either with the default option or with

To use (for Integrity servers) or compile also with the option.
To use any of these functions, make sure your program includes and link
in the math library by specifying on the compiler or linker command
line.
