Hello,
Is there an absolute value function for ODK forms? I'm trying to add a
constraint that takes the absolute value of the difference of two numbers.
I did a search of this forums previous absolute value questions, but I did
not understand the answers.
Any insight you can offer is appreciated.
Thank you
Musyoka,
I don't think there is an abs method. Bug report at
https://code.google.com/p/opendatakit/issues/detail?id=998. Code
contributions are welcome.
In the meanwhile, take the difference of the numbers, and then use a
calculate to find the abs. The formula will look something like this..
if (/data/difference < 0, /data/difference * -1, /data/difference)
