BaseForm

BaseForm[expr,n]

prints with the numbers in expr given in base n.

Details

  • The maximum allowed base is 36. For bases larger than 10, additional digits are chosen from the letters az. »
  • You can enter a number in an arbitrary base using base^^digits. »
  • When a number in an arbitrary base is given in scientific notation, the exponent is still given in base 10. »
  • You can mix BaseForm with NumberForm and related functions. »
  • BaseForm acts as a "wrapper", which affects printing but not evaluation.
