Very few hardware RISC CPU FPU's implement transcendental functions directly; and, last I heard, none of the "Palm Ready" ARM CPU's even had an FPU. For non-armlet code, the interfaces to MathLib are very easy to use. The libm source is well tested code of high accuracy. There's also source code to implement your own trig functions in the book "Advanced Palm Programming". And depending on your performance or accuracy needs, the simple series approximations for exp() and log() might work. I used the latter in the cbasPad5 armlet in order to keep the code smaller and more cache friendly. IMHO. YMMV.
