Hello guys,

I have some code where str2int function return incorrect value with minus sign. It doesn't match the parameter and also it adds "-" sign. What does that mean? I'm sure that it accepts the variable of the string type.

One of the examples:

str2int("2711838385");

it returns integer = -1583128911

never faced such things before.

The customer uses str2int64 instead of str2int.

Use str2int64 instead.

int is a 32 bit integer, with range of -2,147,483,647 to 2,147,483,647. Your value is higher and the compiler do a overflow in the memory allocated.

I got that 2711838385 is too big for int but str2int64 doesn't help also. It proceeds to return minus value.
