Bug #4894: incorrect conversions from BigDecimal to Float

I am working with BigDecimals, and was previously using floats. I came across this strange bug where when converting from BigDecimal down to float, zeros in the middle of the number get removed.

require 'bigdecimal' #=> true
require 'bigdecimal/util' #=> true

BigDecimal.new("40.08").to_f #=> 40.8

which are obviously 2 very different numbers. This happens with implicit converisons too:

BigDecimal.new("48.08") - 40.00 #=> 8.8

if this has already been fixed, my apologies.

You're using old release of ruby1.8.7.

It seems already fixed at ruby1.8.7p334.

Please be sure to use latest version before reporting bug.

Thanks,
