In CSynthMT32.cpp on line 3105 the following statement appears:

float filval = abs((((float)lf - 7.0) * 12.0) / 7.0);

Is the use of abs as opposed to fabs correct that is to say is filval assumed
to be an integer value? The only place filval is used is as the second
parameter(exponent) in a pow function which expects a floating point
variable.
