Incorrect currency ratio equality when low valued unit converted to high valued #252
Description
Describe the bug
Converter rounds/truncates rate to 4 decimal places, therefore currency ratio of low valued units such iranian rial or indonesian rupiah compared to highly valued units like US dollars displayed incorrectly.
Steps To Reproduce
- Launch the calculator
- Open the currency converter
- Select Iranian rial as first unit and US dollar as second.
- See today's exchange rate.
Expected behavior
Ideally ratio should be rounded appropriately, not too much and not too little. Basically converters round it to 6 decimals. E.g 1 IRR = 0.000024 USD
