Large enough to get a value's magnitude back into [2^-511,2^511] from Double.MIN_VALUE or Double.MAX_VALUE, and small enough not to get it across that range (considering a 2*53 tolerance due to only checking magnitude of min/max value, and scaling all values together).
HYPOT_MAX_MAG - Static variable in class net.jafama.CmnFastMath
For using sqrt, to avoid overflow/underflow, we want values magnitude in [1/sqrt(Double.MAX_VALUE/n),sqrt(Double.MAX_VALUE/n)], n being the number of arguments.
hypot_NaN(double, double) - Static method in class net.jafama.CmnFastMath
At least one of the arguments must be NaN.
