(n: BigDecimal): booleanChecks whether a given BigDecimal is negative.
When to use
Use to test whether a BigDecimal is less than zero.
Example (Checking negative decimals)
import { BigDecimal } from "effect"
import * as assert from "node:assert"
assert.deepStrictEqual(BigDecimal.isNegative(BigDecimal.fromStringUnsafe("-1")), true)
assert.deepStrictEqual(BigDecimal.isNegative(BigDecimal.fromStringUnsafe("0")), false)
assert.deepStrictEqual(BigDecimal.isNegative(BigDecimal.fromStringUnsafe("1")), false)predicates
