f32 sqrtD = (f32)sqrt(determinant); ---> isn't faster to call f32 sqrtD = sqrtf(determinant);?

yeah, but the result of this square root still have to be converted into a f32
--> f32 sqrtD = (f32)sqrtf(determinant);

but the effect won't be very high

No - sqrtf returns float not double...

i know that sqrtf returns a float, but you have to convert it in f32 anyway
