convert - convert an expression to a different form

	Calling Sequence
	convert(expr, form, arg3, ...)

Parameters

expr	-	any expression
form	-	name
arg3, ...	-	(optional) other arguments

Description

•

The convert function is used to convert an expression from one form to another. Some of the conversions are data-type conversions, for example convert([x, y], set) Others are form or function conversions, for example convert(x^3-3*x^2+7*x+9, horner, x) yields 9+(7+(-3+x)*x)*x and convert(a*x!, GAMMA) yields a*GAMMA(x+1).

•	For function conversions, a set of optional arguments to perform the conversion in different manners are described in convert/to_special_function.

•	The types of known conversions are (the second argument form must be one of these):

•	Further information is available under help pages convert/form where form is one of the forms from the above list.

•

A user can make custom conversions known to the convert function by defining a Maple procedure in the following way. If the procedure `convert/f` is defined, then the function call convert(a, f, x, y, ...) will invoke `convert/f`(a, x, y, ...); Note that the procedure may be indexed, for example convert([1,2,3], Vector[row]);

Examples

Convert can be used to convert numbers between bases. See the help pages convert/decimal, convert/base, convert/binary, convert/octal, and convert/hex for more information and examples.
