Conversion formula

[antandkate]

Hi,
Is it possible to use conversion functions in family formulas?
For example take a length value and convert it to a string (text) value? similar to the vba functions.
syntax(length,fix)
converttostring(500.0,1) = "500.0"
converttostring(500.0,0) = "500"

Also a function to join strings similar to the one in excel
syntax(string1,string2,........)
concentrate("string1","string2") = "string1string2"

Cheers
Anthony
