How to add float numbers using JavaScript ?

Given two or more numbers and the task is to get the float addition in the desired format with the help of JavaScript. There are two methods to solve this problem which are discussed below:

 Approach 1:

Example: This example implements the above approach. 

Javascript




let val = parseFloat('2.3') + parseFloat('2.4');
console.log("2.3 + 2.4 = " + val);
 
function gfg_Run() {
    console.log("2.3 + 2.4 = "
        + (parseFloat('2.3') +
            parseFloat('2.4')).toFixed(2));
}
gfg_Run()


Output

2.3 + 2.4 = 4.699999999999999
2.3 + 2.4 = 4.70

Approach 2:

Example: This example implements the above approach. 

Javascript




let val = parseFloat('2.3') + parseFloat('2.4');
console.log("2.3 + 2.4 = " + val);
 
function gfg_Run() {
    console.log("2.3 + 2.4 = " +
        Math.round((parseFloat('2.3')
            + parseFloat('2.4')) * 100) / 100);
}
gfg_Run()


Output

2.3 + 2.4 = 4.699999999999999
2.3 + 2.4 = 4.7
