Issue

The row_total_incl_tax is returned as a near-zero residual value in the order API response instead of 0.00 for fully discounted items.

Steps to reproduce:

  1. Create a product with a price and a special price. Go to Catalog > Products > Click Add Product > set Price to $25 and Special Price to $16.99 under Advanced Pricing.
  2. Go to Stores > Taxes > Tax Zones and Rates and add a 20% rate. Then go to Tax Rules and create a rule and assign
    Taxable Goods as the product tax class.
  3. Create a sales rule with a 100% discount and a coupon. Go to Marketing > Promotions > Cart Price Rules and add a rule with a 100% discount and then use Specific Coupon and enter your code.
  4. Go to Stores > Settings > Configuration > Sales > Tax > and configure tax settings.
  5. Enable free shipping. Go to Stores > Settings > Configuration > Sales > Delivery Methods > Free Shipping. Set Enabled to Yes and adjust settings.
  6. Go to the product page and select Add to Cart. Go to the shopping cart and apply the coupon code.
  7. Place the order with the applicable tax zone.
  8. Generate an admin token (API) via REST API.
  9. Retrieve order details via REST API.
  10. Check row_total_incl_tax in the response.

Expected results:

row_total_incl_tax should return a currency-appropriate value like 0.00 when the item is fully discounted.

Actual results:

row_total_incl_tax returns a near-zero floating point value like 3.5527136788005e-15, which is not appropriate for currency display.
