Why am I getting the wrong result when using float? [duplicate]

Answer 1

Because you are using float. Float is an extremely approximate value. Always use it with an Epsilon (maximum error allowance) when comparing.

I am guessing you are getting result = 0.02999999?

Answer 2

I guess you are refering to deviations cause by Floating point arithmetics. You can read about in in the provided link.

If you really need to make the calculation 100% accurate, you can use decimal instead of float.

Answer 3

Floating point maths is likely to contain rounding approximations, see the many duplicate questions on this site, or read here:
