In the table of the Wikipedia page you have linked there is written:

C (ISO 1990)     %     Implementation defined

C (ISO 1999)     %     Dividend[1]

Where the reference [1] is:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf, section 6.5.5

6.5.5.5 paragraph says:

>The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder.In both operations, if the value of the second operand is zero, the behavior is undefined.<


> As I cited, there are FOUR different standards on this, not including the C99
> "implementation defined" one.

But by far the most common ones are two of them (counting languages: 45+
Dividend, 31+ Divisor, and 8 something different).
