TONUMBER lost information in conversion

[JJXVI123]

Hello,

I am trying to create a workflow that will separate out totals of three columns represented by the data point share class. I am having a problem converting the string into a number (double) because of the $ in front of the digits. I am using the formula  tonumber(replacechar([$ DIFF],"$,","")) but I am getting a TONUMBER: lost information in conversion error. I suspect this is because the $ DIFF column has spaces. I tried to use the TRIM formula but I cannot get it to work and I suspect I am doing something wrong. How can I add TRIM to the formula I have already created.

Hi @JJXVI123 ,

If you want to trim right after replacing the char, you can use like this:

tonumber(trim(replacechar([$ DIFF],"$,","")))

If this function still doesn't work, please share a sample of your dataset for me to look into it.

Best,

Thank you very much @fmvizcaino but it looks like that was not the problem, I needed to create another workflow line for $ DIFF and that has mostly worked, the problem I am having now is that the $ DIFF column has negative numbers represented by parenthesis EX (1.09). When I run the formula for tonumber(replacechar([$ DIFF],"$,","")) it is removing the $ but it is also turning the negative numbers into 0's and I am not sure why.

Almost there. Try this,

tonumber(replacechar(replacechar([Field1],"$,) ",""), '(', '-'))

Hi @JJXVI123 ,

Alteryx cannot convert automatically numbers with parenthesis into negative numbers. We need to remove it manually as example attached.
