(n: BigDecimal): BigDecimalProvides a negate operation on BigDecimals.
When to use
Use to flip the sign of a BigDecimal.
Example (Negating decimals)
import { BigDecimal } from "effect"
import * as assert from "node:assert"
assert.deepStrictEqual(BigDecimal.negate(BigDecimal.fromStringUnsafe("3")), BigDecimal.fromStringUnsafe("-3"))
assert.deepStrictEqual(BigDecimal.negate(BigDecimal.fromStringUnsafe("-6")), BigDecimal.fromStringUnsafe("6"))math

const make: (
value: bigint,
scale: number
) => BigDecimal
Creates a BigDecimal from a bigint value and a scale.
When to use
Use to construct a decimal directly from its unscaled integer value and
decimal scale.
Example (Creating decimals from bigint and scale)
import { BigDecimal } from "effect"
// Create 123.45 (12345 with scale 2)
const decimal = BigDecimal.make(12345n, 2)
console.log(BigDecimal.format(decimal)) // "123.45"
// Create 42 (42 with scale 0)
const integer = BigDecimal.make(42n, 0)
console.log(BigDecimal.format(integer)) // "42"
