I'm trying to use a negative value in a string which is in a hash.
{"amount"=>"-50.01", "currency"=>"CAD"}
If I write transaction.amount I get 0.5001E2, if I use to_f I get 50.01.
I'm trying to extract the -50 value.
Thank you for your help!
Try
transaction['amount']
For example
a = {"amount"=>"-50.01", "currency"=>"CAD"}
Then
a['amount']
returns '-50.01'

I'm working with a script that only takes integer values. I'm reading from a CSV with a timestamp example of 12:34. Is there a way I get ruby to read it as an integer?
Not sure if you are dealing with a Time object. If so:
str = Time.now.to_s[/\d\d:\d\d:\d\d/]
=> "19:04:53"
str.gsub(":", "").to_i
=> 190453
If it's a string just start with the sub:
"12:34".sub(":", "").to_i
=> 1234

Just as the title implies, is it acceptable to create and use a collection from within a magento template file?
I would say no, use blocks for this
