NAME
       cproj(),	 cprojf(),  cprojl(),  cprojw(),  cprojq()  -  functions  that
       project all infinities onto the one on the positive real axis

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns its argument z, except if the argument is  a  complex  infinity
       (even  if  it is a complex infinity which has one infinite part and one
       NaN part), then returns a positive infinity  on	the  real  axis,  with
       imaginary  part	z  It  is intended as an aide for modeling the Riemann
       sphere.

       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.

       These functions raise no exceptions.

USAGE
       To use these functions, compile with the default option.	 To  use  com‐
       pile with the option.  Make sure your program includes Link in the math
       library by specifying on the compiler or linker command line.

ERRORS
       No errors are defined.

SEE ALSO

       metic'')
