Frequently Asked Questions

Do leading zeros change the value?

Leading zeros do not change an integer’s value. They can still matter when a value must occupy a fixed number of bits or characters.

Should I round numbers before calculating?

Keep the original input precision through the calculation and round the final answer to the precision you need. Rounding an intermediate result can change later steps.
