Today like other days I was working on a game in ruby. Like any game this game uses a lot of rand(). Writing code for this game I came across this little quirk/feature of ruby. When dividing two integers ruby will return an integer. EG…
>> 10 / 2 => 5
Thats fine but what about the following…
>> 100 / 56 => 1
Ruby in this case did not return a float like I expected. It returned a rounded integer. To get a float make sure your dividing two floats.
>> 100.to_f / 56.to_f => 1.78571428571429
Thats more what I expected. So maybe you already worked this out but it was a slight trip up for me.
