yeah, I'm sort of stuck in a rails 1.2.x time warp and am struggling
with a bunch of the changes in 2.3.x - thus, it wasn't really the big
decimal thing of mysql that was the problem.
I forgot about to_f because frankly, I never used it. I primarily am
concerned with view code here so I had just stuck that code to extend
the Float class (which worked so well in 1.2.x)...
class Float
def to_fl(digits)
sprintf("%.#{digits}f",self)
end
end
and I could get a fixed number of digits whenever I wanted. Apparently
this is like a very ineffective way to go about things in 2.3.x and to_f
gives me whatever decimal places it believes are significant so I'm sort
of trying to figure out how to locate the magic genie again.
