Detailed Description

template<class TYPE>
class Gaudi::Math::Lomont< TYPE >

The equality comparison of double numbers using as the metric the maximal number of Units in the Last Place (ULP).

It is a slightly modified version of very efficient implementation of the initial Bruce Dawson's algorithm by Chris Lomont.

C.Lomont claims the algorithm is factor 2-10 more efficient with respect to classical Knuth's algorithm for comparison of the floating number using the relative precision.
