A **fraction** is a ratio of two integers. Fractions are traditionally
written "2/3" but Calc uses the notation ``2:3'`. (The `/` key
performs RPN division; the following two sequences push the number
``2:3'` on the stack: `2 : 3 RET`, or

Fractions may also be entered in a three-part form, where ``2:3:4'`
represents two-and-three-quarters. See section Fraction Formats, for fraction
display formats.

Non-decimal fractions are entered and displayed as
`` radix#num:denom'` (or in the analogous three-part
form). The numerator and denominator always use the same radix.
