Description
Steps to Reproduce
- Go to https://app.uniswap.org/#/swap?theme=dark&inputCurrency=eth&outputCurrency=0xB8235B60471396211A2f22EcbB9e5778c7fcC4f5
- Set "0.1" in ETH
- You will see "8.979717e+9" when you should see "8979710000"
- Not only "8.979717e+9" cannot be understood by anyone not dealing with scientific representation of numbers, the input containing "8.979717e+9" cannot be edited or deleted either, making it impossible to round the number to the next decimals (sometimes needed for tax tokens)
Expected Behavior
You will see "8.979717e+9" in the output amount when you should see "8979710000"
@uniswap/widgets also upgraded to this recently making it impossible to use regular numbers on the widget prior 2.1.5-something
Additional Context
Also happening with $SHIB for instance:

Research direction
Start with the swap output amount in the interface reached from the provided reproduction URL, then review the related @uniswap/widgets behavior and version note. The fix is done when large token amounts display as regular decimal strings rather than scientific notation and the resulting input remains editable and deletable.
