 Fixed-point numbers are basically normal (32-bit) integers, which count 65536ths instead of entire units, offering better precision than integers but limiting the range of values.
 The upper 16 bits are used for the integer part and the lower 16 bits are used for the fraction (65536ths).
 Since they are still akin to integers, you can use them in normal integer expressions, and some integer operators like
