The string() command converts any expression to its string form. This applies to numbers, but also to lists, matrices, symbolic expressions, and equations. The result depends on all the mode settings that are typically involved with displaying a number: base, exact/approx setting, etc.


The main use of string() is with output commands like PtText, PxlText, Text, Title, etc. These commands only work with strings, so for any other data type, you'll have to use string() first — & will also come in handy. For example:

:Text "The value of x is: "&string(x)

If you're just converting numbers, you might also want to look into format(), which only applies to numbers and also puts them in a specific form.

Advanced Uses
