If one has to calculate a fraction of a given int value, say:
int j = 78;int i = 5* j / 4;Is this faster than doing:
int i = 1.25*j; // ?If it is, is there a conversion factor one could use to decide which to use, as in how many int divisions can be done in the same time a one float multiplication?
Edit: I think the comments make it clear that the floating point math will be slower, but the question is, by how much? If I need to replace each float multiplication by Nint divisions, for what N will this not be worth it anymore?
