Price tiers calculated on 2 decimals even when prices of 4 decimals are entered issue solved.

[JettyRohanAditya]

Description (*)

• magento2/app/code/Magento/Quote/Model/Quote/Item/AbstractItem.php
• Here there is a function calcRowTotal() that is setting the total
• there $total = $this->priceCurrency->round($this->getCalculationPriceOriginal()) * $qty; is setting the total by multiplying get calculation price with the quantity
• here they are rounding the get calculation price
• And that round is from
• magento2/lib/internal/Magento/Framework/Pricing/PriceCurrencyInterface.php
• There is one implementation of this at magento2/app/code/Magento/Directory/Model/PriceCurrency.php
• Here they were given precision as 2 which was doing the wrong calculations,
• I changed it with self::DEFAULT_PRECISION which is 4.

2. For the Front End

• magento2/app/code/Magento/Catalog/view/base/web/js/price-utils.js
• changed form
• precision = isNaN(format.requiredPrecision = Math.abs(format.requiredPrecision)) ? 4 : format.requiredPrecision;
• To
• precision = !isNaN(format.requiredPrecision = Math.abs(format.requiredPrecision)) ? format.requiredPrecision : 4;

• magento2/lib/internal/Magento/Framework/Pricing/PriceCurrencyInterface.php
• changed CONST DEFAULT_PRECISION = 4; from 2.

Hi @JettyRohanAditya. Thank you for your contribution!
Here are some useful tips on how you can test your changes using Magento test environment.

Add the comment under your pull request to deploy test or vanilla Magento instance:

• @magento give me test instance - deploy test instance based on PR changes
• @magento give me 2.4-develop instance - deploy vanilla Magento instance

❗ Automated tests can be triggered manually with an appropriate comment:

• @magento run all tests - run or re-run all required tests against the PR changes
• @magento run <test-build(s)> - run or re-run specific test build(s)
  For example: @magento run Unit Tests

<test-build(s)> is a comma-separated list of build names.

Allowed build names are:

1. Database Compare
2. Functional Tests CE
3. Functional Tests EE
4. Functional Tests B2B
5. Integration Tests
6. Magento Health Index
7. Sample Data Tests CE
8. Sample Data Tests EE
9. Sample Data Tests B2B
10. Static Tests
11. Unit Tests
12. WebAPI Tests
13. Semantic Version Checker

You can find more information about the builds here
ℹ️ Run only required test builds during development. Run all test builds before sending your pull request for review.
