 |
|
I'm just going to get right to the point.
I need to malloc an int enough space to hold 1000 digits.
I'm not sure how to allocate enough bytes equivalent to 1000(+1) digits.
Can anybody help me out here?

| Code: | | malloc( ceil((floor(log(pow(10, 1000))/log(2)) + 1) / 4) ) |
The math is right, good luck finding a data type to hold pow(10, 1000).

Flyte I don't understand. Because wouldn't all that add up to just a number? when it actual wants the size in bytes.

Are you implying that a size is not a number?

So then
| Code: | | int result = (int)malloc( ceil((floor(log(pow(10, 1000))/log(2)) + 1) / 4) ) |
should work? I really am getting confused. lol
All i need is to make a variable able to hold 1000 digits. I know one way of doing this is using malloc. But i don't know exactly how.
