Do float division with `fdiv`
Usually in ruby, when I need to perform floating point division I call
.to_f on either the numerator or denominator, like this:
1 / 5.to_f # 0.2
While many people might read this as floating point division instead of integer division, reading it that way gets trickier when those numbers are variables and the
.to_f happens somewhere else.
You can be more explicit about the operation you are performing with
1.fdiv(5) # 0.2
This works with floats as well, so that you can use
fdiv in any context.
1.to_f.fdiv(5.to_f) # 0.2
