Decimal , Float and Double Difference

What is the Difference between Decimal , Float and Double Values?

float 7 digits of precision

double has about 15 digits of precision

decimal has about 28 digits of precision

If you need better accuracy (eg: in accounting applications), use double instead of float. In modern CPUs both data types have almost the same performance. The only benifit of using float is they take up less space. Practically matters only if you have got many of them.
