Hi all

Why is 3/2=1 in a Rais view? How can I get Rails to output 1.5 as the  
result?

Thanks  
Josh

That’s a common ruby gotcha. Division of integers results in an  
integer. To fix, convert one or both numbers to floats with .to\_f or  
include a decimal place on the literal (e.g., 3.0/2)

At least one of the numbers needs to be a float. Here’s an example of  
script/console output:

Loading development environment (Rails 2.1.1)

> > 3/2  
> > =\> 1
> 
> > 3.0/2  
> > =\> 1.5
> 
> > 3/2.0  
> > =\> 1.5
> 
> > 3.0/2.0  
> > =\> 1.5

In Ruby, division of integers returns only the integer part of the  
result.
