Roman Numerals / 1

1 in Roman Numerals

I

1 = I (1). That's I, purely additive. 1 splits into 1 (I), together forming I. There's no Roman numeral below I — the Romans had no symbol for zero, so I (1) is the floor of the system. At 1 symbol, I is compact for 1. 1: 1 Arabic digit, 1 Roman symbol, for 1. In binary, 1 is 1, 1 bits long for 1.
