Sine-wave reference generation using math library

Hi,

I saw some examples using 'Sine' function from math library to generate internal sine-wave reference for their applications.

I am just wondering if I can also use this method in a fixed-point micro-controller (i.e. F28035) ?

Usually, I use a look-up table from IQmath to do this, what should I be aware of if I use this sine function directly from the math library ?

Thank you,

Frank
