Divide and Get Remainder at the same time?

Question

Apparently, x86 (and probably a lot of other instruction sets) put both the quotient and the remainder of a divide operation in separate registers.

Now, we can probably trust compilers to optimize a code such as this to use only one call to divide:

( x / 6 )
( x % 6 )

And they probably do. Still, do any languages (or libraries, but mainly looking for languages) support giving both the divide and modulo results at the same time? If so, what are they, and What does the syntax look like?

Answer 1

Common Lisp does: http://www.lispworks.com/documentation/HyperSpec/Body/f_floorc.htm

Answer 2

    int result,rest;
    _asm
    {
        xor edx, edx // pone edx a cero; edx = 0
        mov eax, result// eax = 2AF0
        mov ecx, radix // ecx = 4
        div ecx
        mov val, eax
        mov rest, edx
    }

Answer 3

This return the result an de remainder

        int result,rest;
    _asm
    {
        xor edx, edx // pone edx a cero; edx = 0
        mov eax, result// eax = 2AF0
        mov ecx, radix // ecx = 4
        div ecx
        mov val, eax
        mov rest, edx
    }

Answer 4

The .NET framework has Math.DivRem:

int mod, div = Math.DivRem(11, 3, out mod);
// mod = 2, div = 3

Although, DivRem is just a wrapper around something like this:

int div = x / y;
int mod = x % y;

(I have no idea whether or not the jitter can/does optimise that sort of thing into a single instruction.)

Answer 5

In Java the class BigDecimal has the operation divideAndRemainder returning an array of 2 elements with the result and de remainder of the division.

BigDecimal bDecimal = ...
BigDecimal[] result = bDecimal.divideAndRemainder(new BigDecimal(60));

Javadoc: https://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html#divideAndRemainder(java.math.BigDecimal)

Answer 6

In C#/.NET you've got Math.DivRem: http://msdn.microsoft.com/en-us/library/system.math.divrem.aspx

But according to this thread this isn't that much an optimization.
