Gets <code>''x''</code> [[Modulo operation|modulo]] <code>''y''</code>, or the remainder after <code>''x''</code> has been divided by <code>''y''</code>. This is accurate for integers up to 2<sup>53</sup>; for larger integers Lua's modulo operator may return an erroneous value. This function deals with this problem by returning <code>0</code> if the modulo given by Lua's modulo operator is less than 0 or greater than <code>''y''</code>.
