Fixed point arithmetic numbers have a very limited range which leads to them not playing well with multiplication and division (doing scientific computation with them is a game of searching which division|multiplication got you that 0|+inf and then searching for an alternative formula if one such formula even exists, they are much more fragile than IEEE-754). They are not used that often so people are unfamiliar with their shortcomings but, I would not make them the default. Here is little bit of information on them: https://pages.tacc.utexas.edu/~eijkhout/istc/html/arithmetic.html#Fixed-pointarithmetic https://pages.tacc.utexas.edu/~eijkhout/istc/html/arithmetic...
