Why are there two ways to multiply arbitrary signed numbers in MIPS? But looking at the machine code it appears that mult is a valid R-type instruction (opcode 0) whereas mul has a nonzero opcode (0x1c) and so shouldn't be an R-type, even though it contains 3 registers?! RISC philosophy says to use pseudo-instructions frequently since we only have limited real instructions
Under what circumstances are __rmul__ called? - Stack Overflow Say I have a list l Under what circumstance is l __rmul__(self, other) called? I basically understood the documentation, but I would also like to see an example to clarify its usages beyond any d
MUL Instruction in x86 Assembly - Stack Overflow The x86 mul instruction always multiplies the accumulator register (EAX, AX, or AL) by whichever operand you provide in the instruction: The dword-sized mul ecx will multiply EAX with ECX and leave its double-length product in the register combo EDX:EAX
assembly - Should I use mul or imul when multiplying a signed . . . You can replace imul with mul, and the result would still be the same (-10) Are mul and imul exactly the same when multiplying a signed number to an unsigned number, or is there a difference between them?
mysql - SQL keys, MUL vs PRI vs UNI - Stack Overflow What is the difference between MUL, PRI and UNI in MySQL? I'm working on a MySQL query, using the command: desc mytable; One of the fields is shown as being a MUL key, others show up as UNI or P
Using the __mul__ method with a number and different class object I am working on a class for polynomials and I would like to use the mul method to multiply two different polynomials when both inputs are polynomials, but also be able to use the method to multiply a polynomial with a scalar
How to use Fused Multiply-Add (FMA) instructions with SSE AVX The compiler is allowed to fuse a separated add and multiply, even though this changes the final result (by making it more accurate) An FMA has only one rounding (it effectively keeps infinite precision for the internal temporary multiply result), while an ADD + MUL has two The IEEE and C standards allow this when #pragma STDC FP_CONTRACT ON is in effect, and compilers are allowed to have it
masm - Multiplication in assembly - Stack Overflow I am trying to create an assembly program that calculates the factorial of a number: data n dword 1 res dword 1 code start: mov ecx, 5 Top: add n, 1 mov eax, res mov ebx, n mul eax, ebx mov res
