floating-point

I use doubles for a uniform implementation of some arithmetic calculations. These calculations may be actually applied to integers too, but there are no C++-like templates in Java and I don't want to duplicate the implementation code, so I simply use "double" version for ints.

Does JVM spec guarantees the correctness of integer operations such a <=,>=, +, -, *, and / (in case of remainder==0) when the operations are emulated as corresponding floating point ops?

(Any integer, of course, has reasonable size to be represented in double's mantissa)

So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did. I understand that the computation is faster… >>> More
