a fraction. Function Qπ converts a floating-point value into a fraction of π,
if a fraction of π can be found for the number; otherwise, it converts the
number to a fraction. Examples are of these three functions are shown next.
Out of the functions in the REWRITE menu, functions DISTRIB, EXPLN,
EXP2POW, FDISTRIB, LIN, LNCOLLECT, POWEREXPAND, and SIMPLIFY
apply to algebraic expressions. Many of these functions are presented in this
Chapter. However, for the sake of completeness we present here the help-
facility entries for these functions.
