I want to perform addition of floating point numbers. I will always have always have only 2 decimal places.
However if I do:
var num = 0;
num += parseFloat("2434545.64").toFixed(2);
num += parseFloat("454560.91").toFixed(2);
I get the value as 02434545.64454560.91
It is appending instead of adding. Also will the addition be accurate always?
toFixed() return a String.
So you concatenate two String.
You should use toFixed() only in the last statement and you should not mix this invocation with a += operator in a even statement because here :
num += parseFloat("2434545.64").toFixed(2);
parseFloat("2434545.64").toFixed(2) is evaluated first.
It produces a String.
Then its num += String result is evaluated.
So, it would concatenate a Float with a String. Which produces again a String concatenation and not an arithmetic operation.
Just invoke toFixed() in a distinct statement :
var num = 0;
num += parseFloat("2434545.64");
num += parseFloat("454560.91");
num = num.toFixed(2);
Here you go with the solution
var num = 0;
num += 2434545.64;
num += 454560.91;
console.log(parseFloat(num).toFixed(2));
Here is the documentation for parseFloat https://www.w3schools.com/jsref/jsref_parsefloat.asp
