Hi, Besides the fact that you can enable such optimization...
Thus, I never cared of writing i.e float x = a * 0.1f but I always wrote float x = a / 10.f trusting the compiler.
This article look at this specific case: https://doi.org/10.1145/103162.103163 (Page 29, section 3.2.3), it's old but describe some interesting things about float numbers.
Therefore, in this example is better to use x = a / 10.f :-) Best, Sebastian
