> `optional` **allowNegative?**: `boolean`

Defined in: [core/src/utils/token-amount.ts:143](https://github.com/B3Pay/ic-reactor/blob/f1956947ae037304fce1675a38695964c1aa9e32/packages/core/src/utils/token-amount.ts#L143)

Accept a leading `-`, for an `int` amount. Defaults to `false`: a ledger's

rather than failing later when the call is encoded.
