Adding float values using jQuery
used code:
result variables:
subtotal = 4.6;
tax = 2.3;
Total = parseFloat(subtotal)+parseFloat(tax);
i got result 6.8999999999999995... why it not returning the correct value 6.9
Use toFixed() like
Total =Total.toFixed(1);
Or Simply,
Total = (parseFloat(subtotal)+parseFloat(tax)).toFixed(1);

I was goofing around when I decided to try to show a varaible on the console. this is my JS
test = 8888888888888888888;
console.log(test)
however, on the console, this was shown:
Why did 8888888888888888888 go to 8888888888888889000?
The number is larger than the largest value that can be represented exactly in a double-precision floating point value. Modern runtimes expose a constant on the Number constructor with the maximum value (Number.MAX_SAFE_INTEGER). The value is 9007199254740991.

Why the result of this data is doesn't give the exact value expected by a human brain or expected output of a person to appear
16.08 * 100 = 1607.9999999999998;
When i tried it to the console developer of the chrome browser;
and i tried using
console.log(16.08*100); gives 1607.9999999999998
Supposedly the answer that i should be seeing is
16.08 * 100 = 1608;
will you please help me with these. or any explanations
use .toFixed(n) method of javascript.
console.log((16.08 * 100).toFixed());

My application works fine, but sometimes it return "strange" result, I dont't understand why it happens. For ex:
var a = 80.78, b = 83.49, c = 45.33
alert (a+b+c); //209.59999999999997 instead of 209.60
Thanks
