Successor of INT MAX and INT MIN

Question

I have two inquiries.

Is 1e9 smaller than the INT MAX number from the climits in the header file?

Is -1e9 larger than the INT MIN value from the climits header file?

In general, whenever I need to utilise a large positive integer or a tiny negative number in my application, I use INT MAX or INT MIN.

But, if there are any limits, such as not using header files to construct your software, may I use 1e9 and -1e9 as the greatest and lowest numbers?

Answer 1

If you use a long instead, the answer to both of your inquiries is yes.

Prior to C++20, its minimum range was -2147483647 to +2147483647, which was sufficient.

(Consider an int with a minimum range of -32767 to +32767.)

In addition, starting with C++20, the minimum is -2147483648, thus signed integral types become easier to deal with.
