How 256 is written

256 is the sum of its place values, 200 + 50 + 6, and is written two hundred fifty-six.

Its ordinal form is two hundred fifty-sixth — only the final element takes the ordinal ending — and on a check the amount line reads "Two hundred fifty-six and 00/100", where 00/100 stands for zero cents.

British English inserts "and" before the last part, giving two hundred and fifty-six, where American English writes two hundred fifty-six without it.

256 is 2 to the power of 8, so its binary form is a 1 followed by 8 zeros (100000000) and its hexadecimal form is 100.
