Decimals in the sandbox
Specifier: @nodetool-ai/sandbox-decimal. One module, decimal.js. Import it
at the top of the body.
Exact sums
import Decimal from "@nodetool-ai/sandbox-decimal";
const total = inputs.amounts
.reduce((sum, n) => sum.plus(n), new Decimal(0));
return { total: total.toFixed(2) };
Divide without float noise
import Decimal from "@nodetool-ai/sandbox-decimal";
const share = new Decimal(inputs.cents).div(inputs.parts);
return { share: share.toFixed(2) };
Gotchas
- Default export.
import Decimal from "@nodetool-ai/sandbox-decimal". - Pass strings or Decimals.
new Decimal(0.1)already lost precision; usenew Decimal("0.1"). - The guest has no Intl. Format with
toFixed/toString, nottoLocaleString.
