This function is useful if a floating point comparison requires a
certain precision. The return value can be considered as the precision.
For instance, if you want to compare two 32-bit floating point values
and all you need is a 24-bit precision, you can use this function like
this:
if (qFloatDistance(a,b) < (1 << 7)) { // The last 7 bits are not
// significant
// precise enough
}
