The function BaseForm[] is found in the v3.0 Help Browser under Built-in
Functions/Number Formatting/BaseForm

BaseForm[expr, n] prints with the numbers in expr given in base n.=20

The maximum allowed base is 36. For bases larger than 10, additional digi=
ts
are chosen from the letters a=96z.=20

You can enter a number in an arbitrary base using base^^digits.=20

When a number in an arbitrary base is given in scientific notation, the
exponent is still given in base 10.=20

You can mix BaseForm with NumberForm and related functions.=20

BaseForm acts as a "wrapper", which affects printing, but not evaluation.=

See the Mathematica book: Section 2.8.7 and=A0Section 3.1.3. [i.e. book's=
3rd
Edition for v3.0]
