[quote author="Aken" date="1258444330"]Actually I was rather unfamiliar with the float column type in databases. I assumed it was similar to a PHP float. [/quote]
As my PHP example illustrates, the PHP float is subject to the same errors in calculation. This is inherent to the float data type.
One would expect that floor((0.1+0.7)*10) would be 8, not 7. This could be a major issue if you run any form of E-Commerce.
Quote:I never did say that a float is the best resource to use, though. I said it works fine for me.
I wonder about that. Maybe you haven't noticed it because you always assumed that float calculations wouldn't influence the outcome.
Quote:And suggested that people always sanitize their numbers relating to money BEFORE entering them into a database, and not using it to round off numbers and such.
Sanitation doesn't help here. It is inherent to the way computers do floating point calculations. See my PHP example.
