Doing a floating unit without installing additional gems?

Let's say I have these two floats:

a = 50.0
b = 1048576.0
c = a/b

c

When I print it out , I get the following:

4.76837158203125e-005

Doing division with calc.exe

gives me the result 0.0000476837158203125. Is there a way to achieve the same with Ruby without installing any additional gems?

You can format floats using Ruby string formatting like:



irb> "%.019f" % c
=> "0.0000476837158203125"
