## Description

You're often stuck with numbers that don't fit into standard calculator inputs. Maybe you're working with massive integers that require BigInt support or trying to map out a custom encoding system where the math gets messy. This MCP handles the heavy lifting of base conversion for you. Instead of hunting for online tools that cap out at certain digits, you can just tell your AI client to convert a value from base 10 to base 36, and it'll give you the exact result. It handles fractions too, so you won't lose precision on the decimal side of things. If you're trying to learn the logic behind the math, it can actually walk you through the division and multiplication steps. It's a solid way to keep your data accurate when moving between binary, hex, or custom positional notations. You'll find it's a reliable part of the Vinkius catalog for any dev work involving low-level data representation.

## Tools

### convert_number
Converts a value from one base to another with high precision for fractions.

### get_conversion_trace
Provides a step-by-step breakdown of the math used in a conversion.

### validate_alphabet_compatibility
Checks if a custom set of symbols is valid for a target base.

## Prompt Examples

**Prompt:** 
```
Convert the decimal number 1048576 to base 36.
```

**Response:** 
```
The decimal number 1048576 in base 36 is: **2Y000**

| Base | Value |
| :--- | :--- |
| Decimal | 1048576 |
| Base 36 | 2Y000 |
```

**Prompt:** 
```
Show me the conversion steps for converting 25 to base 3.
```

**Response:** 
```
Here is the step-by-step breakdown for converting **25** from base 10 to base 3:

1. **25 / 3** = 8, remainder **1**
2. **8 / 3** = 2, remainder **2**
3. **2 / 3** = 0, remainder **2**

Reading the remainders from bottom to top, the result is **221**.
```

**Prompt:** 
```
Is the alphabet 'ABC' valid for base 3?
```

**Response:** 
```
Yes, the alphabet **'ABC'** is a valid sequence of 3 unique symbols for base 3. It contains exactly 3 unique characters, which matches the requirements for a base-3 system.
```

## Capabilities

### Convert large integers
Turn massive numbers into any base from 2 to 36 without losing precision.

### Handle fractional numbers
Convert decimals between bases while maintaining your specific precision requirements.

### Generate math traces
Get a step-by-step breakdown of every division and multiplication in a conversion.

### Validate custom alphabets
Check if your custom symbol set actually works for a specific base size.

### Support high-precision math
Use BigInt logic to ensure accuracy for numbers that exceed standard limits.

## Use Cases

### Custom Encoding Validation
A developer wants to know if a specific set of 10 symbols is valid for a base-11 system. They ask the agent to check the alphabet.

### Educational Math Walkthroughs
A student asks for the step-by-step division needed to convert the number 13 into binary to understand the remainder logic.

### BigInt Data Migration
An engineer needs to convert a massive 20-digit integer from decimal to hex for a legacy system and needs to ensure no digits are dropped.

### Fractional Base Conversion
A researcher needs to convert a precise decimal value to a base-12 system while keeping exactly 8 decimal places of accuracy.

## Benefits

- No more rounding errors on big numbers because it uses BigInt logic for every conversion.
- See the math clearly with get_conversion_trace so you can verify every step of the process.
- Save time on custom encoding by using validate_alphabet_compatibility to check your symbols instantly.
- Handle complex fractions without losing accuracy by setting specific precision levels.
- Move between any base from 2 to 36 without hunting for specialized online calculators.

## How It Works

The bottom line is you get precise numeric conversions without worrying about overflow or rounding errors.

1. Tell your AI client which number to convert and which bases to use.
2. The MCP processes the value using high-precision BigInt math.
3. You get the final converted value or a full step-by-step trace.

## Frequently Asked Questions

**Can the Number Base Converter handle very large numbers?**
Yes, it uses BigInt logic to handle integers that are far too large for standard calculators or basic programming floats.

**Does the Number Base Converter support fractions?**
It does. You can convert fractional numbers between bases while specifying the precision you need to keep the results accurate.

**How do I see the math steps for a conversion?**
You can ask your AI client to provide a conversion trace. It will then show you every division and multiplication step used to reach the final result.

**What bases can the Number Base Converter handle?**
It supports any base from 2 all the way up to 36.

**Can I check my own custom alphabet with the Number Base Converter?**
Yes, you can use the validation tool to check if your custom symbol set is compatible with a specific base size.

**Will it round my numbers during conversion?**
It is designed for high precision. You can configure the precision for fractions to ensure the output matches your requirements exactly.
