Addition

Addition is a mathematical operation that represents combining collections of objects together into a larger collection

Division

In mathematics, division (÷) is an arithmetic elementary operation.

Math operation in a While

"The division operator has a higher order precedence as the addition operator"

Is golden section search better than binary search?

"I don t know how division modulo both works but division modulo both s much more complex than addition subtraction or even multiplication"

What is the performance impact of using int64_t instead of int32_t on 32-bit systems?

"Usually simple operations like addition subtraction and multiplication are very fast;division is a bit slower"

from question  

How do I measure the FLOPS my C# app uses?

"Since most processors can do an addition comparison or multiplication in a single cycle those are all counted as one flop;but division always takes longer"

from question  

What is FLOP/s and is it a good measure of performance?

"The addition and subtraction is okay because the types of a and b force them to be performed using floating point arithmetic - but because division binds more tightly than addition and subtraction it s like using the brackets above only the immediate operands are considered"

from question  

To return a double, do I have to cast to double even if types are double in c#?

from question  

What is the performance impact of using int64_t instead of int32_t on 32-bit systems?

"Division is much more expensive than multiplication;in addition calculating an approximate reciprocal is much more simd-friendly since there are usually reciprocal estimate instructions that provide a starting point which can be refined by the newton-raphson method"

from question

Example

"Best example the division it an an addition are both o 1 but usually the division takes far more cycles time to execute than the addition"

Others

Example

For multiplication the technique described at is a reasonably easy thing to implement and is better than serial addition;division is more complex in general but a good place to start is

from question  

Why is Sieve of Eratosthenes more efficient than the simple "dumb" algorithm?

So even disregarding the trial division is more expensive than addition and multiplication we see that the number of operations the sieve requires is much smaller than the number of operations required by trial division if the limit is not too small

from question  

Why is Sieve of Eratosthenes more efficient than the simple "dumb" algorithm?

Think of long division - you do a series of subtract - shift operations and you don t know what you need to do next until you have completed the previous part of the operation;for addition it is easier to see how you could achieve a complete operation in one cycle

An attempt to understand what a Clock cycle is through example

In addition to that the crossing off may be less work than a division don t know about python it is for c arrays

from question  

Why do two algorithms for finding primes differ in speed so much even though they seem to do the same number of iterations?

I think division by a power of 10 other than 10 9 would be somewhat cheap but would require an actual division on each limb and propagating the remainder to the next limb;extended-precision addition is somewhat more expensive this way than with binary limbs because i have to generate the carry-out manually with a compare unsigned comparison

from question  

Integer division algorithm

Use float a b instead or add a from __future__ import division to the top of your file;tentative conclusion using a for-loop and simple addition method1 is a lot faster than any of the list comprehension methods for this example
