Actually, the C standard does not require that (-30) % 7 == (-2). The
standard has somewhat loose requirements here that would allow the C "%"
operator to behave either like the Ada "rem" operator, or like the Ada "mod"
operator. The drive to standardize C, unfortunately, came after there were
many divergent implementations of the language. The need to validate
existing implementations tied the hands of the standards committee.
