Suppose, we have a floating-point number −
2.74
If we divide this number by 4, the result is 0.685.
We want to divide this number by 4 but the result should be rounded to 2 decimals.
Therefore, the result should be −
3 times 0.69 and a remainder of 0.67
Example
The code for this will be −
const num = 2.74; const parts = 4; const divideWithPrecision = (num, parts, precision = 2) => { const quo = +(num / parts).toFixed(precision); const remainder = +(num - quo * (parts - 1)).toFixed(precision); if(quo === remainder){ return { parts, value: quo }; }else{ return { parts: parts - 1, value: quo, remainder }; }; }; console.log(divideWithPrecision(num, parts));
Output
And the output in the console will be −
{ parts: 3, value: 0.69, remainder: 0.67 }
