0x12C0

0x12C0 is a hexadecimal numeral written with the 0x prefix that denotes a base-16 value. In decimal it equals 4800, and in binary it is 0001 0010 1100 0000.

In programming languages that adopt C-style literals, 0x12C0 expresses the integer value 4800. In Python you can write 0x12C0 and get 4800; in Java and JavaScript similarly. JSON does not support hexadecimal numeric literals, so 0x12C0 would not be valid in JSON data.

Common contexts where such hex literals appear include memory addresses, bit masks, color component values in certain formats, or machine opcodes.

It is part of the wider hexadecimal numeral system, used to represent binary data succinctly; base-16 uses digits 0-9 and A-F.
