[Oberon] Modulus on negative number

[Srinivas Nayak]

Dear All,

Recently I come across modulus on a negative number.
Will it produce a negative number or positive?
Someone says both are correct! http://stackoverflow.com/a/4403556
Which one is mathematically correct?
Surprisingly different languages calculate it differently even!
What is Oberon's way?


With thanks and best regards,

Yours sincerely,
Srinivas Nayak
