Digit Validation

Before any conversion, we ensure each digit is valid for your “From Base.” For instance, base-2 only accepts “0” and “1.” Entering “2” triggers an error.

Smart Omissions

• If fromBase=10, no table parse steps (we already have decimal).
• If toBase=10, skip repeated division steps; result is just decimal.
• No fractional part, skip fraction logic.

Typical Flow

1. Check if digits fit the chosen base (0..base-1).
2. If needed, parse to decimal showing digit×power breakdown.
3. If needed, convert decimal to target base via repeated division/multiplication.
