Commit Message:

Line 14: slightly slower than the old one (96 seconds vs 70 seconds). This issue
I think the scale/precision should already be substituted by codegen though 
(the Expr::GetConstant()) function is a magic function that we replace with the 
constant value during codegen. It would be good to understand why it's slower, 
although obviously it's better to be slightly slower and correct :)
