BloombergLP::bdlb::DoubleCompareUtil::fuzzyLe

Return true if the specified a and b satisfy the fuzzy less‐equal relation (denoted "a ~le b") as defined by the expression: ` fuzzyCompare(a, b, relTol, absTol) == e_LESS_THAN or == e_EQUAL ` and false otherwise. Optionally specify the relative tolerance relTol, or relTol and the absolute tolerance absTol, used to determine fuzzy less‐equal. If an optional tolerance argument is not specified, a reasonable (implementation‐dependent) default value for that tolerance is used. Note that if either absTol or relTol is 0.0, that aspect of fuzzy comparison is effectively suppressed, but the behavior of this function is defined. The behavior is undefined unless both 'relTol` and `absTol` are non‐negative, finite numbers (which excludes NaN and infinity).
