I’m currently doing the last project of javascript algorithm.
Here is my code
console.log(60 + 20 + 15 + 1 + 0.50 + 0.20 + 0.04)
the output is 96.74000000000001
the problem seems to be the last number “0.04” if I change it to “0.03” or “0.05” it works fine.
You have discovered one of the problems with floating point values. Computers can’t exactly store decimal numbers, so the arithmetic will have rounding errors.
I recommend using a whole number of cents instead. No decimals means no rounding.
