function(number, decimals, trailingZeros = false, minDecimals = 2, significantRounding=false)
If absolute number is greater than zero (num > 0) then minDecimals and normal formatting is used.
rounding(123.123456, 5); //Outputs 123.12
rounding(123.100000, 5); //Outputs 123.10
rounding(123.100000, 5, true, 4); //Outputs 123.1000
rounding(1234.12, 2, true, 2, true) //Outputs 120.00
If absolute number is less than zero (num < 0) then maxDecimals and significant rounding is used.
rounding(0.0000123456789, 5); //Outputs 0.000012346
rounding(0.0123456789, 5); //Outputs 0.012346
rounding(0.012, 5); //Outputs 0.012
rounding(0.012, 5, true); //Outputs 0.012000
rounding(0.0123001, 5, true); //Outputs 0.012300
