isSmallerNumbersBetween function
Compares two doubles and determines if the a
value is smaller than the b
value to within the tolerance or not. Equality comparison is based on
the binary representation.
Implementation
bool isSmallerNumbersBetween(double a, double b, int maxNumbersBetween) {
// If A or B are a NAN, return false. NANs are equal to nothing,
// not even themselves, and thus they're not bigger or
// smaller than anything either
if (a.isNaN || b.isNaN) {
return false;
}
return compareToNumbersBetween(a, b, maxNumbersBetween) < 0;
}
