Non-EU dataset decimal format incorrect (commas instead of periods) in [course/datasets/non-eu-dataset]

[vamsivk18]

Description

The non-EU dataset contains numeric values that use commas (,) as decimal separators, such as 3,14. This formatting is expected for EU datasets, but non-EU regions typically use periods (.) — for example, 3.14.

This inconsistency may lead to incorrect parsing or calculation errors when processing or analyzing the data, especially in systems expecting standard non-EU numeric formats.

Affected Files

• course/datasets/non-eu-dataset/big-dataset/Orders.csv
• course/datasets/non-eu-dataset/small-dataset/Orders.csv
• course/datasets/non-eu-dataset/small-dataset/Orders_Archive.csv

Expected Behavior

• EU dataset: 3,14 ✅
• Non-EU dataset: 3.14 ✅

Actual Behavior

• Non-EU dataset: 3,14 ❌

Impact

• May cause parsing errors in data visualization
• Could result in incorrect numerical calculations
• Breaks consistency in formatting between datasets

Suggested Fix

Standardize decimal formatting in the non-EU dataset to use periods (.) instead of commas (,).

Additional Info

Please confirm if this is the intended format. If not, I’d be happy to submit a pull request with a fix.

Is it possible to fix the above issue by myself remotely?
It would be great if you could share something useful because I am currently learning the course and I am facing difficulty.
