OK, this is not unique to select2 ...
Say,
process = sin(!);
compiles to
output0[i0] = FAUSTFLOAT(std::sin(float(input1[i0])));
Or,
process = atan2(1,!);
results in
output0[i0] = FAUSTFLOAT(std::atan2(1.0f, float(input1[i0])));
and please note that
process = atan2(!,1);
generates the same code
output0[i0] = FAUSTFLOAT(std::atan2(1.0f, float(input1[i0])));
I feel this has something to do with boxPrimX() logic, but I am not
sure...
