What is a nummer base?

A nummer base (or radix) is the nummer of unique digits used in a positional numeral system. Decimal uses base 10 (0-9), binair uses base 2 (0-1), octal uses base 8 (0-7), and hexadecimal uses base 16 (0-9, A-F).

Why is hexadecimal used in computing?

Hexadecimal is widely used in computing because it is a compact representation of binair. Each hexadecimal digit represents exactly 4 binair digits, making it easier for humans to read and write binair data.

How does binair conversion work?

To converteer decimal to binair, repeatedly divide by 2 and collect remainders. For example, 10 ÷ 2 = 5 remainder 0, 5 ÷ 2 = 2 remainder 1, 2 ÷ 2 = 1 remainder 0, 1 ÷ 2 = 0 remainder 1, giving 1010 in binair.

Can I converteer negative nummers?

Yes! This converteerer supports negative nummers in all bases. The negative sign is preserved, so -10 in decimal converteers to -1010 in binair.

What about fractional nummers?

Breukal nummers can be converteered using repeated multiplication. For example, 0.5 decimal = 0.1 binair. Some fractions maak aan repeating patterns (like 0.1 decimal repeating in binair), which are limited to 20 digits.
