Hi.,

I am working with CodeWarrior v10.6 and of MQX v4.0.

I want a function that is calculating Standard Deviation. is there any provision in am math.h .

I tried to search it on math.h but helpless to get it.

Hi Utsavi Bharuchwala,

from what I know, math.h doesn't have a function to support standard deviation, but it can support some other floating point calculation, for instance sqrt() -- Square Root Calculation.

to get floating point calculation working, we must set compiler tool:

Tool Settings->Librarian->Model->c9x

The EWL library has a smaller footprint but doesn’t support floating point calculations.

I suggest you refer this thread for more information:

Have a great day,
