Why is division in Ruby returning an integer instead of decimal value?
It’s doing integer division. You can use to_f to force things into floating-point mode:
9.to_f / 5 #=> 1.89 / 5.to_f #=> 1.8This also works if your values are variables instead of literals. Converting one value to a float is sufficient to coerce the whole expression to floating point arithmetic.
It’s doing integer division. You can make one of the numbers a Float by adding .0:
9.0 / 5 #=> 1.89 / 5.0 #=> 1.8
