SL, ITC

Get the total of all number values of a given list

Sample Input:
TotalList ("1¶.22¶.11¶xyz")
Sample Output:
1.33


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

All the credits to Mr Geoff Wells (http://www.dataisland.com) who had written the original one.
Because the use of LeftWords() and RightWords() Geoff's CF was not able to properly add any numbers less than 1 to the total.
For example: TotalList (".11¶.22¶1") returned as result 34 instead of 1.33
Now TotalList (".11¶.22¶1") returns 1.33
Why the old CF was wrong?
LeftWords() and Rightwords() use not-alphanumeric chars as word's separators so:
LeftWords(".11¶.22¶1" ; 1) returns "11".
LeftValues(".11¶.22¶1" ; 1) instead returns .11

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Discuss:

Is there a situation where the following non-recursive function wouldn't accomplish the same task?

Evaluate ( "Sum ( GetAsNumber ( \"" & Substitute ( valueList ; "¶" ; "\" ) ; GetAsNumber ( \"" ) & "\" ) )" )
