Common problems (FAQ).
There are a number of questions about floating point which
are regularly asked on the Linux and other newsgroups.
Frequently asked questions and answers.
IEEE Floating Point
There are IEEE standards for floating point.
There are good points
and bad points to these
standards on Linux.
An Intel FPU emulator
I am the author and maintainer of an
FPU emulator for the
Intel 80x86 architecture.
This emulator is a (optional) standard part of Linux,
and is available for DJGPP and *BSD.
I have placed some information on the emulator,
including information on bugs,
There is some software available which is useful
in connection with floating point computation:
- paranoia tests floating point arithmetic
Software for the Linux operating system.
You can down-load some floating-point related software
for Linux here:
- A package with code for handling
the floating point environment on x86 machines
based upon the proposed C standard,
and code for handling floating point exceptions.
- Patches to allow gdb to display
and modify the contents of the FPU on x86 machines.
