dotnet Core in value overflow

In. NET core, the int type with C # has a range of upper and lower values, as follows:

int int . MaxValue; int int . MinValue; Console.WriteLine ($"Therange of integers is {min} to {max}");

Run to get results

The range of integers is-2147483648 to 2147483647

At this point, if you execute the following code

int 3 ; Console.WriteLine ($"anexample of overflow: {what}");

Get the range result is

An example of overflow:-2147483646

It's strange that the execution max+3 get the result min+2

Check out the official tutorials

If a calculation produces a value that exceeds those limits, you had an underflow or overflow condition.

If the calculation produces a value that exceeds these limits, a underflow or overflow condition occurs.

Max+3 The overflow occurred, it became min+2.

This is another condition in Python.

Import SYS Print Sys.maxint

Get the maximum value 2147483647

Then perform the following

Print sys.maxint+3

Get 2147483650

See no, no overflow, originally python after int exceeds the maximum value, automatically convert it to a long type, so there is no overflow, as long as the memory is large enough.
