1. Data Display class (use Toprecision rounding and parsefloat to turn into numbers and then display)

//

The encapsulation method is as follows:

function strip (num, precision =) {   return +parsefloat (num.toprecision ( Precision)); }  

2. Data Operation class (for operations such as +-*/, you cannot use toprecision.) The right thing to do is to turn the decimal into an integer and then calculate

Take addition as an example:

function Add (NUM1, num2) {   = (num1.tostring (). Split ('. ') [1] | | "). Length;    = (Num2.tostring (). Split ('. ') [1] | | "). Length;    = Math.pow (Ten, Math.max (Num1digits, num2digits));    return (NUM1 * basenum + num2 * basenum)/ basenum;}
