Since these operators have the same precedence as in the C language,
put expressions in parentheses to avoid ambiguity.
To avoid confusion with register names or with the %hi, %lo, %r_disp32/64, or %r_plt32/64 operators,
the modulo operator % must not be
immediately followed by a letter or digit. The modulo operator is typically
followed by a space or left parenthesis character.
