Save float values in SQL Server
10,470
Solution 1
You're not actually trying to save 123.66, because you can't represent 123.66 exactly as a float or double. The database is saving the data more accurately than you're used to, that's all.
If you want to save decimal numbers accurately, use the decimal
type.
See my articles on floating binary point and floating decimal point types for more info.
Solution 2
This is not a database issue, but a general problem with floating numbers
