Hi can anyone let me know the logic to convert the string into number with two decimal using inbuilt JavaScript methods

The input value is a JSON string

Ex1: 123 just need to convert to 1.23

Ex2: 153 to 1.53

Ex3: 100 to 1.00

I suggest dividing by 100 by also using toFixed(2) to ensure that we always end up with at most two decimal places, which seems to be part of your reporting requirement.

var input = 123.456;
console.log(input);
output = (input / 100).toFixed(2);
console.log(output);

JavaScript Convert String to Number, stringstream() : This is an easy way to convert strings of digits into ints, floats or doubles.

console.log((Number('123') / 100).toFixed(2));
console.log((Number('100') / 100).toFixed(2));
console.log((Number('156') / 100).toFixed(2));

Converting Strings to Numbers in C/C++, If entered data is in number format, we need to convert the string to an int. To do so, we use Integer.parseInt() method. Signature. The parseInt() is the static method  Another way of converting numerics to strings is using the format () function, which allows you to set placeholders within a string and then convert another data type to a string and fill the placeholders. To use the function, simply write a string followed by.format () and pass the arguments for the placeholders.

console.log((Number('123') / 100).toFixed(2));
console.log((Number('100') / 100).toFixed(2));
console.log((Number('156') / 100).toFixed(2));
console.log((Number('100') / 100).toFixed(2));

You can use the inbuilt Number() function to convert the string to a number, then divide by 100:

function convertNumber(input) {
    return (input) ? (Number(input) / 100).toFixed(2): null;
}

console.log("Result:", convertNumber("123"));
console.log("Result:", convertNumber("153"));
console.log("Result:", convertNumber("176"));
console.log("Result:", convertNumber("100"));
console.log("Result:", convertNumber(null));

  • Like... var output = inputValue / 100;?
  • stackoverflow.com/questions/6095795/…
  • That will fail in case of 100.
  • 100 has to get convert into 1.00
  • use this (input/100).toFixed(2)
  • a string, divided by a number will be auto-coerced to number. So you don't need Number().
  • Understand @31piy
  • 100 /100 give 1 not 1.00
