For division and modulus, Awk should act like C.

'''Exponentiation's note:''' With [[nawk]] or [[gawk]], <code>$1 ** $2</code> acts like <code>$1 ^ $2</code>. With [[mawk]], <code>$1 ** $2</code> is a syntax error. Nawk allows <code>**</code>, but its manual page only has <code>^</code>. Gawk's manual warns, ''"The POSIX standard only specifies the use of `^' for exponentiation. For maximum portability, do not use the `**' operator."''
