Parallax - Floating Point Coprocessor

Archiver

Hello Parallax friends,



I want to introduce you to the Micromega um-FPU (Floating Point
Coprocessor). The uM-FPU is a 32-bit floating point coprocessor that
can be easily interfaced with the BASIC Stamp(r) microcontroller (BS2,
BS2e, BS2sx, BS2p24, BS2p40 or BS2pe) or Javelin Stamp microcontroller
to provide support for 32-bit IEEE 754 floating point operations and
long integer operations. For either microcontroller, the set up only
requires 2 pins.



The direct link below contains the complete description and
documentation or just click on the link at www.parallax.com
<http://www.parallax.com/>

For complete details check out the .pdf manuals and source code files
which are very thorough and well written.

Have a great day.



Best Regards,

Erik Wood

In the <umfpujavelinstamp.pdf> document on page 5:

// value = |value|
value.negate();

This should probably be:

// value = |value|
value.abs();

This happens again on page 9 for integers.

Looks kool otherwise. Just wish Java had operation overloading so I could
use algebraic notation instead of having to call all those methods. (minor
***** ;-)
