`Digits()`

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static int`	`closest_log2(int x)`
`static double`	`getPercent(double x)` return a number [0..1] as a percent value xx.yy
`static double`	`getWithDecimals(double x, int n)` get number x with n decimals
`static void`	`internal_test()` testbench.
`static int`	`log2_ceil(int x)`
`static int`	`maxUniquePairs(int n)` given a set of n elements, return the number of unique pairs
`static double`	`numberDivided(double n, long div)` return `n'` in as n' = n * div, with two decimals
`static void`	`printNumber(long n)` print the number `n` in the format xxx K/G/M
`static void`	`printNumber1024(long n)` same as printNumber, bit this time, K = 1024, not 1000
