While working on a project, I came across a JS-script created by a former employee that basically creates a report in the form of
Name : Value Name2 : Value2
etc.
The peoblem is that the values can sometimes be floats (with different precision), integers, or even in the form 2.20011E+17
. What I want to output are pure integers. I don't know a lot of JavaScript, though. How would I go about writing a method that takes these sometimes-floats and makes them integers?
The Math. round() method rounds a number to the nearest integer. 2.49 will be rounded down (2), and 2.5 will be rounded up (3).
Use the toFixed() method to round a number to 2 decimal places, e.g. const result = num. toFixed(2) . The toFixed method will round and format the number to 2 decimal places.
To round a number to the nearest 5, call the Math. round() function, passing it the number divided by 5 and multiply the result by 5 .
The Math. round() function in JavaScript is used to round the number passed as parameter to its nearest integer. Parameters : The number to be rounded to its nearest integer.
If you need to round to a certain number of digits use the following function
function roundNumber(number, digits) { var multiple = Math.pow(10, digits); var rndedNum = Math.round(number * multiple) / multiple; return rndedNum; }
