Method getDigits

Returns the number of digits to display the number n with resolution 'resolution'; (if n is integer and small enough to display without scientific notation, no decimals are needed, irrespective of 'resolution') Scientific notation is used for more than 'maxDigits' (must be >=3), and indicated by

(double n, double resolution, int maxDigits, int suggestedDigits)
