Math Object List:

For Amateur Radio enthusiasts working with Microwaves and GPS stabilized oscillators I produced two chips for 3Dfix detection and display of other GPS parameters. The first thing I did when ...

Object for converting the output of the Sensirion SHT11 to a more usable form.

This is a simple SPIN CRC8 object. You can send either a string or a pointer to a byte array. I'll add CRC16 and CRC32 at some point but right ...

Date/Time contains two objects to handle calendar dates and times. Demos are provided to show the function of each method. One handles a byte string with year, month, day, hour, ...

A modified version of Float32Full that allocates cogs dynamically. Somewhat slower than the original, but only uses up one cog, and can be shared between multiple objects. Just call it ...

Update to the dynamic math lib. It's faster and occupies about half the space as it used to.

This PST application shows the first Fixed-point arithmetic library object on OBEX. The "SPIN_TrigPack" object is a complete Fixed-point package with the basic trigonometric functions for robot and navigation projects. ...

IEEE-754 compliant Propeller floating point math package for functions callable by both Spin and assembler code. Contains Float32, Float32Full, Float32A and documentation. (V1.4 - updated Exp, Exp10, Log, Log10)

Floating point math demo uses tv_terminal, FloatMath and FloatString objects.

This is an update to the FloatString object. It adds the FloatToFormat routine to return a string of up to 9 characters with the specified number of decimal points. (e.g ...
