I attach two screen shots. At least in my opinion the \pi/2 is too low in the math input mode. This is on Mac.
This may be a matter of spacing between the fraction bar and the character. One day I will try to understand the rules implemented in the TeXbook and compare them to what we actually do. I have been doing that for other parts (in 2.3 the spacing between characters), but it takes a lot of time to get right.
