BloombergLP::bdlb::DoubleCompareUtil::fuzzyNe

Return whether a and b satisfy fuzzy inequality.

Synopsis

Declared in <bdlb_doublecompareutil.h>

static
bool
fuzzyNe(
    double a,
    double b);

Description

Return true if the specified a and b satisfy the fuzzy inequality relation (denoted "a ~ne b") as defined by the expression: ` fuzzyCompare(a, b, relTol, absTol) != e_EQUAL ` and false otherwise. Optionally specify the relative tolerance relTol, or relTol and the absolute tolerance absTol, used to determine fuzzy inequality. 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).
