MUL (Multiply) is one of the opcodes in the DCPU-16 specification. It represents a multiplication of two numbers.

[edit] Usage
MUL arg1, arg2
MUL multiplies arg1 by arg2 and stores the low 16 bits of the result in arg1. The high 16 bits are stored in the EX register.
[edit] Signing awareness
MUL is only designed to handle unsigned numbers. For signed numbers, use MLI.
[edit] Overflow handling
The higher 16 bits of the result are stored in the EX register.
[edit] Processing
In binary machine code, this Basic opcode's five-bit representation is: 0b0 0100 (0x04)
The instruction has a takes two cycles to execute, plus any additional cycles necessary to evaluate the arguments.
