BigDecimalAsNumberSerializer

JSON serializer for BigDecimal that preserves numeric precision.

Encodes BigDecimal as an unquoted JSON number literal (not a string), which is important for PostgreSQL's JSONB type to correctly interpret the value as a number rather than text.

Usage Example

@Serializable
@DynamicallyMappable("tribute_amount")
data class TributeAmount(
    val province: String,
    @Serializable(with = BigDecimalAsNumberSerializer::class)
    val amountInDenarii: BigDecimal
)
