Yes, there is trig support

ABS - Absolute Value
COS - Cosine
SIN - Sine
DCD - set bit

weee here we go
The Basic Stamp SIN operator breaks the circle down into 0 to 255 units instead of 0 to 359 degrees. Some textbooks call this unit a binary radian or brad. Each brad is equivalent to 1.406 degrees. And instead of a unit circle, which results in fractional sine values between 0 and 1. BASIC Stamp SIN is based on a 127-unit circle. Results are given in two's complement form in order to accommodate negative values. So, at the origin, SIN is 0. At 45 degrees (32 brads), sine is 90. At 90 degrees (64 brads), sine is 127. At 180 degrees (128 brads), sine is 0. At 270 degrees (192 brads), sine is -127.

To convert brads to degrees, multiply by 180 then divide by 128. To convert degrees to brads, multiply by 128, then divide by 180.


I hope this explains it, any questions?
