how to parse float in javascript like c# float?

Question

I am newbie to javascript, forgive me if i ask this kind of question

in c# I have :

(float)3772/32767 = 0.115115821

but in javascript i have :

3772/32767 = 0.11511581774346141

I heard there is a function parseFloat but it does not fix my problem

I want the result to be like the c# float result, because in javascript side it brings some noise to my final data, how to cast like a c# float ?

You can use the toFixed() or toPrecision() methods to change the precision of float-numbers:

let number = 3772/32767;

console.log(number);

console.log(number.toFixed(7));

console.log(number.toPrecision(8));

Yes but I also want the last two digits

No matter what significance you round to it'll never be 0.115115821, since 17 is either rounded to 2 or 177 is rounded to 18

yes I agree, this was just an example, i have thousands of operations , each operation needs its own precision

And since floating point math is very different between c# and js you're unlikely to get the same number when you're talking about billionths
