[Tinyos-help] Calculation precision (in micaz and telosb)

[Rémi Villé]

Hi,

In TinysOS there's only integer type to get calculation results. I think
because of microcontroller/CPU coercions.
But I would like to know if there is a precision during the calculation, I
mean if I do (1/4) * 100 (using brackets to obtain 0.25 before the
multiplication), will I obtain 25 or 0 ?

Is there logarithm and exponential functions in TinyOS ?
Is it possible to do ln(0.7) and obtain a good result precision ?

Thanks,

Rémi
