BloombergLP::bdlb::DoubleCompareUtil

This struct provides a namespace for a suite of fuzzy (equality and relational) comparison functions on pairs of double values, parameterized by (optionally specified) relative and absolute tolerances. Note that all methods are naturally thread‐safe, and well‐behaved for all tolerance values.
