decimal to any base converter

Write an interactive program to convert decimal integers to another base.

Program must handle all positive integers up to a reasonable range.

All target bases from 2 to at least 16 must be allowed.

The program must handle invalid input in a reasonable manner and must be user-friendly.

The program must allow the user to continue 'playing with it' until the user wishes to quit.

 

Testing:

Test your program on at least the following numbers:

Target Base	numbers to convert
1	----
17 [33 if doing to base 32]	----
2	0,  1, 16,  65,535 65,535,  1,048,575,  1,048,576, 2,147,483,647, 2,147,483,648  {-7, -1, -15, -29}
10	-30, -7, -10, 0, 1, 10, 72, 1,048,576
20	1,000,000

BONUS:

1. include all target bases from 2 to 32

2. - include negative values

a) expresses as values with a preceding '-'

b) expressed as a compliment (must show absolute value as well)

3. show conversion process step by step

4. include numbers with a fractional part
