MAths function with unsigned integer assigned a negative number
I am trying to convert a C programme to a scrip basic language.
The C programme is fairly simple but produces unexpected results - it is the unxpected result that I would like to emulate with script basic.
I am hoping someone can explain the mechanism that the C programme is using to come up with the unexpected result, then I will try and put that in practice in script basic using the available functions.
The C programme:
Normally if you divide -248625283 by 256 you would get a result of -971192 (integer)
unsigned int crc;
printf("crc before div by 256 %d\n", crc);
printf("crc is a negative number to start with \n");
printf("crc after divide by 256 and assigned to an unsigned integer equals %d decimal \n", crc);
Similarly if you divide 248625283 by 256 you would get a result of 971192.
The programme above gives a result of 15806023 . I expect this is related to assigning a negative number to a unsigned integer. What I need to know is how to get this result (15806023) using basic maths functions.
I hope someone can help explain the mechanism that gives 15806023 when dividing -248625283 by 256.
