Hi, Just a quick question.

When BigInteger converts a string in a specific base, the letters it  
outputs  
are upper case. In MRI the letters are in lower case. Is there a  
specific  
reason for them to be in uppercase in BigInteger - for instance does  
IronPython use uppercase?

Would it be acceptable to change the

```
    private static void AppendRadix(uint rem, uint radix, char[] 

```

tmp,  
StringBuilder buf, bool leadingZeros) {

```
        const string symbols = 

```

“0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ”;

to

```
    private static void AppendRadix(uint rem, uint radix, char[] 

```

tmp,  
StringBuilder buf, bool leadingZeros) {

```
        const string symbols = 

```

“0123456789abcdefghijklmnopqrstuvwxyz”;

Alternatively, the down casing could be done in the Bignum.to\_s(radix)  
method but this seems wasteful.
