- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

.Sh SYNOPSIS
|
|
.In complex.h
|
|
.Ft double
|
|
.Fn cproj "double complex z"
|
|
.Ft float
|
|
.Fn cprojf "float complex z"
|
|
.Ft long double
|
|
.Fn cprojl "long double complex z"
|
|
.Sh DESCRIPTION
|
|
These functions compute a projection of
|
|
.Ar z
|
|
onto the Riemann sphere:
|
|
.Ar z
|
|
projects to
|
|
.Ar z ,
|
|
except that all complex infinities (even those
|
|
with one infinite part and one NaN part) project to positive infinity on the
|
|
real axis.
|
|
If
|
|
.Ar z
|
|
has an infinite part, then
|
|
.Fn cproj
|
|
shall be equivalent to:
|
|
.Bd -literal -offset indent
|
|
INFINITY + I * copysign(0.0, cimag(z))
|
|
.Ed
|
|
.Sh RETURN VALUES
|
|
These functions return the value of the projection onto the Riemann sphere.
|
|
.Sh ERRORS
|
|
No errors are defined.
