The practical problem
A target inch dimension needs a valid combination of gage blocks. The supported target range is 0.0500 through 1.0000 inches.
The solution
The browser-based calculator accepts an inch target and returns an exact block combination when one is available.
Input validation and calculation reliability
Input is validated before calculation. Valid targets are evaluated for an exact block combination, keeping the result clear and bounded by the supported range.
Responsive cross-device usability
The calculator is responsive and has been verified on desktop, tablet, and phone.
Testing and verification
Its permanent automated test suite contains 55 passing tests, covering the calculator’s verified behavior.
