Base-N Number Validator
Verify if a number string is mathematically valid for any chosen radix (base 2 through 36). Designed for software developers, electrical engineers, students, and computer architecture researchers requiring deterministic client-side accuracy.
Enter a string and select the radix to test.

Active DerivationWhat Is Base-N Number Validator?
The Base-N Number Validator confirms whether an input string adheres strictly to the rules of a specified base N (where 2 <= N <= 36).
How Does It Work?
Scans every character and ensures its digit value is strictly less than N. Reports invalid characters and index locations.
Mathematical Algorithm
Step-by-Step Example
Important Rules & Edge Cases
- Every character must be less than the base.
Practical Applications in Engineering
- Form input validation before running radix conversions in code.
- Sanitizing user inputs.
Common Mistakes to Avoid
- Caution: Testing a number against the wrong base.
Frequently Asked Questions
Can a number valid in base 8 also be valid in base 10?
Yes, because all valid octal digits (0-7) are also valid decimal digits.
