My logic calculates and returns a value based on user input, I want to modify that value to always have three decimal digits
For example;
1
to 1.000
1.02
to 1.020
2.000004
to 2.000
2.5687
to 2.569
How would I achieve it on javascript?
You can use Number().toFixed()
to do it
const formatVal = (val,precise = 3) =>{ return Number(val).toFixed(precise) } console.log(formatVal(1,3)) console.log(formatVal(1.02,3)) console.log(formatVal(2.000004,3)) console.log(formatVal(2.5687)) console.log("-----------------") console.log(formatVal(2.5687,2))
You can do something like this,
let newNum = Number(1.34).toFixed(3); console.log(newNum);
