Problem 42758. Convert float to base N

Created by Alberto Comin

The matlab function dec2base converts a positive integer number to a specified base. Extend it so that it works with non integers and negative numbers. For example 10.5 in base16 is 'a.8', and -4 is base2 is '-100'.

The tests are not case-sensitive and check the first 6 digits after the decimal point.

The problem actually considers 6 digits before and after the decimal point in the target base, which means 12 digits. Imho, when stating the number of digits after the decimal point, we must specify the base that we are referring to (since the digit 8 in base 10 is 4 digits in base 2, and the 2-digit number 15 in base 10 is only one digit F in base 16) .
