bug: Grow bitcoin RGas swap interface crash

[nonast]

Rooch version

n/a

What did you do?

On the swap RGas dialog on grow.rooch, I enter a number with a lot of zeros (e.g. 0,000001).

What did you see happen?

The site crashes (turns white) with this error in the browser console:

117-a4bea2e1ac79b24d.js:1 RangeError: The number 1000.0000000000001 cannot be converted to a BigInt because it is not an integer
at BigInt ()

What did you expect to see?

The website should not crash.
