function f_(n){ n = n ? n.split('.') : []; if( !n[0] ){ n[0] = '00'; } if( !n[1] ){ n[1] = '000'; } for(let a=1; a>-1; a--){ if( !n[0][a] ){ n[0] = '0'+n[0]; } } for(let a=0; a<3; a++){ if( !n[1][a] ){ n[1] += '0'; } } return n.join('.'); } for(let x of ['','7', '07', '07.1', '07.10', '17.222']){ console.log( f_(x) ) } – Hanna Rose Dec 28 '22 at 10:55

function formatNumber(number) {
return number.toFixed(3).padStart(6, '0');
}
Does this do the trick for you ?

1don't answer obvious duplicates, flag to close (I didn't downvote, but code only answers are frowned upon) – pilchard Dec 28 '22 at 10:24

But if i use this number e.g 07.1 , it's not working formatNumber(07.1) – Muthukumar Dec 28 '22 at 13:16

@Muthukumar it is because of the 0 in front. Add a step in function that remove the 0 in front when there is one – Johan Dec 28 '22 at 13:24

@Johan if I used this method, -> Number(number).toFixed(3).padStart(6, '0'). It works well. – Muthukumar Dec 29 '22 at 05:12
