Comma as decimal calculation

jstolarek

Having comma as decimal separator also results in nonsense calculation results:

jstolarek This is because the input is interpreted as matrix multiplication

We'd need to figure out how to handle this.

So... any chance to actually be able to type comma as decimal separator?
It's very annoying to have to manually convert it every time. It impacts different queries, including currency conversions.

Similar bug with invalid handling of decimal comma in the currency converter:

pg

Converting currency with a decimal comma fails and gives a buggy looking result.

For example, "123,45 USD in EUR" fails although "123.45 USD in EUR" works.

https://kagi.com/search?q=123%2C45+USD+in+EUR

In Europe, the decimal comma is used instead of a decimal point.

Expecting both "123,45 USD in EUR" and "123.45 USD in EUR" to produce similar results.

This is likely either Kagi internal problem or Wolframalpha problem. I would like Kagi to use System Locale to determine a conversion path both ways so WolframAlpha works correctly. In the meantime I created a custom bang that will work in all 3 cases:

url: https://currencyconverter.io/$3.$4-$1-$2
regex: ^(\w+) (\w+) ([\d]+)[,.]?([\d]*?)$

It works like this: "!cc eur pln 123,34" (also 1000 and 123.34 will work)

btw @Vlad it would be nice to have at least a note what Regexp engine it is under the hood, I assumed JS and it seems correct?

The browser calulator doesnt use comma for decimal, while that would be correct for region the region I've set. (The Netherlands)

As far as I've seen this effects every kind of opperation done on numbers/decimals.

I expected the browser to look at the set region and decide if it should use a comma or period.

This is generally annoying and an inconvenience especially when converting currency.

Please fix, I've seen the issue be in similarish previous reports ranging back 3-4 years ago and this issue has gone unfixed.

Currently if you add commas to you equation Wolfram|Alpha will treat the input as a vector. Given that commas are part of the num pad on keyboards it'd make sense to treat them as decimals instead.

Though, some use commas as thousand separators instead, and dots for decimals, like 1,234.56, which would have to be taken into consideration.

Currently inputs like {1+1,2+2,3+3} with curly brackets doesn't trigger vector calculations. ⟨1+1,2+2,3+3⟩ doesn't either, nor does (1+1,2+2,3+3).

Wolfram|Alpha can reduce this matrix, taken from Wikipedia, {8=2x+y-z,-11=-3x-y+2z,-3=-2x+y+2z}, but the Wolfram|Alpha widget isn't triggered for it. Kagi WA

also the output for some equations returns a comma, due to localisation, but when I type a comma, it gets removed

We have plans in the pipeline to replace the calculator widget with something more robust and interactive!
