hop of those help? The C99 standard specifies ranges of values each type must be able to represent (§5.2.4.2.1). The specified values are minimum magnitude, so nothing prevent from having bigger range. I converted this value to the least number of bits needed to represent number in these ranges on a digital computer. int should be at least 16 bits (range from –32,768 to 32,767) long should be at least 32 bits (range from –2,147,483,648 to 2,147,483,647) long long should be at least 64 bits (range from –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807)

Unexpected value when parsing long long from argv

it should still fix some issue First, C has a builtin modulo operator, %. There's no reason to make your own. Second, your modulo function only takes int values, and atoi returns an int. So your program is limited to the range of an int, not an unsigned long long.

Parsing a long/double/float number when forcing decimal separator

wish helps you As we found out it's got nothing to do with the NumberStyles enumeration but with the datatype you're trying to parse into. You are trying to parse a string that contains a decimal number into an integer value type.

Problem of using unsigned long long int and long long int in program to calculate power of number

wish of those help I have written two functions to find power of positive and negative number in c but it is not printing anything , You're not actually calling the functions: code :
if(number<0)
{
void Calculate_neg_power(number,expo);
}
else{
void Calculate_pos_power(number,expo);
}
if(number<0)
{
Calculate_neg_power(number,expo);
}
else{
Calculate_pos_power(number,expo);
}
int Driver(NUMBER,EXPO, ans);
