How to convert 1k, 3k, 7m, 10m, 10.2m or any formatted value into numbers using java script

September 20, 2022

I want o convert formatted currency values like:
1m
2m
3.789m
100k
20k
80.5b
etc.
into pure numbers using java script how can we achieve that?

>Solution :

This is not a good question (I’m sure someone in the comments will tell you that too), but I’m bored so I’ll give you the code. Here it is:

function convSuffix(str) {
  const suffix = str[str.length-1].toLowerCase();
  if (!isNaN(parseInt(suffix))) return parseInt(str);
  // If you want to allow decimials in the result, then use this 
  // instead of the previous line:
  // if (!isNaN(parseInt(suffix))) return parseFloat(str);
  
  const num = parseFloat(str.slice(0, str.length-1));
  if (suffix === 'k') return num * 1000;
  else if (suffix === 'm') return num * 1000000;
  else if (suffix === 'b') return num * 1000000000;
  else return NaN;
}

console.log(convSuffix("14")) // => 14
console.log(convSuffix("1.34b")) // => 1340000000
console.log(convSuffix("2K")) // => 2000
console.log(convSuffix("7.2m")) // => 7200000
console.log(convSuffix("7.8")) // => 7

You can add more suffixes as you see fit. If there is no suffix, it returns the value, and if it matches no suffix it returns NaN.
