Enter the example value or paste your own input, choose the mode when one is available, and read the first result card for the direct answer. The output area gives a copyable block for code reviews, documentation, API tests, classwork or troubleshooting notes.

What the result means

Signed ranges use two-s complement limits: -2^(bits-1) through 2^(bits-1)-1.

What is not included

The calculator reports mathematical integer ranges, not language-specific overflow behavior.
