Is a sample rate of less than 1% possible

We use the vuejs sentry sdk and as we have quite some traffic on the page would like to further decrease the sample rate.
All the docs always state that the sample rate is in percent, so is it possible to have a sample rate of less than a percent?

  // ...
  tracesSampleRate: 0.001,

Or even lower? Thank you for your help!

The only limit right now is javascript float precision. I would not configure anything that comes close to those limits, but what you’re doing there seems perfectly fine.
