Dropping decimal point

I need to compare a data set in which one batch of data came with currency with decimals such as 246.54 the new data removes the decimals, does not round up, and has just 246... so I need to remove the decimals from the first batch so I can compare. How would I do this without rounding up?

if mynumber >= 0 then 
    mynumber = mynumber.floor
else
    mynumber = 0 - mynumber
    mynumber = mynumber.floor
    mynumber = 0 - mynumber
end

Use the floor function. It gives the first integer smaller than or equal to whatever number you feed it.

1.9.3-p194 :003 > i = 246.54
  => 246.54 
1.9.3-p194 :004 > i.floor
  => 246

You can do a rounding in ruby:

246.54 .to_nearest_i
