I only managed to print 16 bits of accuracy on the embedded board. But
I am not certain that printing the FP value will give me the answer to
how many bits are used. Do anyone else has a better suggestion to how
I could check the accuracy. I cannot find any information about it on
the spesification of the real time OS.

check n in 1 to 80 until 1+(1/2)^n is different from 1
