Numerical Base Converter

This calculator will convert an integer in base 10 format to the corresponding representation in bases 2 - 64. With bases higher than 10 it is necessary to add to the usual numerals, 0 - 9. This is done by using capital letters to represent the numbers 10 - 35 for bases 11 - 36. For example, base 16 uses A through F to represent 10 - 15, respectively. Similarly, the lower case letters are used to represent the numbers 36 - 61 for bases 37 - 62. Finally, to get to base 64 the characters @, and #, represent the numerals 62 and 63. respectively. A table should help to clarify these assignments:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35
a b c d e f g h i j k l m n o p q r s t u v w x y z
36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61
@ #                                                
62 63                                                

This calculator currently handles reals as well as integers in conversions across the same base range, 2 - 64, but only the first and third forms, from base ten to the chosen base(s).

In the first form enter a number in base 10 and the desired base. The calculator returns the number expressed in the chosen base. The second form in the calculator will return the base 10 representation of a number expressed in a different base. The base must be specified. The third form in this calculator will produce a table of all bases [2-9,11-32] and the corresponding representations of any number entered in base 10.
