If'the entry was 360 or more, this will normal lize the degree value to be between and 359 11 the entry was negative the mod operation returns negative value betw een -359 and 0 and further normalization Is rpuired Line 19 tests the result to see if it was negative, and if it was negative, sppe 360 to convert it to the equivalent positive angle correctly in the range 0 to 359 The /mod operation on line 20 takes the normalized degree value off the stack and returns quo ...
