Calculating floating point epsilon/precision in Java

Floating point arithmetic/rounding can be somewhat painful, made worse by the fact that the epsilon (error) in the machine representation of floating point varies depending on the exponent (i.e. how large/small the number being represented is): Normalized numbers when Base = 2, Precision = 3, Exponents = -1 to 2 [Goldberg91] A very comprehensive paper […]
