Is it possible to square a number stored in a register (say eax) without doing any multiplication (by using shifts, etc)? I will be squaring a 16-bit number in 32-bit assembly so overflow shouldn't be an issue. I am using NASM x86 assembly to create the program. Thanks in advance for your help. >>> More

Let me say upfront that the last time I looked at assembly code at any depth was when I was studying Computer Science in Pietermaritzburg – ten years ago – and we never… >>> More
