How can I create a keyword workflow to calculate GST?

[Vincent_Ardern]

I'd love to create a workflow that lets me type in "gst 1000" and have the result become "1150".

 

In my local jurisdiction goods and services tax is 15% on top of the product price. I think if somebody can give me a simple workflow for this then I can tinker with it for the other options around GST inclusive / exclusive. Thanks

Welcome @Vincent_Ardern,

 

There you go.

Thanks @vitor I've added an almost identical script filter so that I can use "gst" as a keyword for either inclusive or exclusive. I've already learnt quite a bit about how each part of the workflow contributes to the outcome thanks to your solution which is relevant to my tasks. (Among other things) I didn't understand how to set the prompt text for each result until now so I'm very happy with this.

 

Hmm. It occurs to me that this is integer values, not float / double. I'll investigate further

That's not true for Vítor's original. Don't know what you've done with your modified version.

It does give you a float as the output but the input is converted to an integer before the calculation. Focused too close on your example, which is funny because I based this on another Workflow I made which did use the input as a float. Easy fix: where you see ARGV[0].to_i, change to ARGV[0].to_f.

Thanks @vitor. I should have updated it myself after I discovered that fix yesterday. I learnt too much about BigDecimal before I realised that the input being converted was the issue. Cheers
