CMath provides trigonometric and transcendental functions for complex numbers.
CMath is a library that provides trigonometric and transcendental functions for
complex numbers. The functions in this module accept integers, floating-point
numbers or complex numbers as arguments.
Note that the selection of functions is similar, but not identical, to that in
module math. The reason for having two modules is that some users aren't
interested in complex numbers, and perhaps don't even know what they are. They
would rather have Math.sqrt(-1) raise an exception than return a complex number.
This is the FreeBSD Ports Collection. For an easy to use
WEB-based interface to it, please see:
https://ports.FreeBSD.org
For general information on the Ports Collection, please see the
FreeBSD Handbook ports section which is available from:
https://docs.freebsd.org/en/books/handbook/ports/
for the latest official version
or:
The ports(7) manual page (man ports).
These will explain how to use ports and packages.
If you would like to search for a port, you can do so easily by
saying (in /usr/ports):
make search name="<name>"
or:
make search key="<keyword>"
which will generate a list of all ports matching <name> or <keyword>.
make search also supports wildcards, such as:
make search name="gtk*"
For information about contributing to FreeBSD ports, please see the Porter's
Handbook, available at:
https://docs.freebsd.org/en/books/porters-handbook/
NOTE: This tree will GROW significantly in size during normal usage!
The distribution tar files can and do accumulate in /usr/ports/distfiles,
and the individual ports will also use up lots of space in their work
subdirectories unless you remember to "make clean" after you're done
building a given port. /usr/ports/distfiles can also be periodically
cleaned without ill-effect.
