Hi, we recently found some oddity when it comes to how perl threats floating point numbers. For example:

>perl -e'print 37.73*100'
3773

while

>perl -e'print int(37.73*100)'
3772

[download]

Although I can workaround it using sprintf or use bignum. I don't understand why perl is intelligent enough to print 3773 when not using int but it is not smart enough to do same thing when using it. I know internally the number might be 3272.999999999999999 and so int chops off the decimal part but shouldn't be consistent?

This represent a legal problem for our application we rely heavily in maths for prizing and charges calculation.
