Module decimal

Defines maximum and minimum values for decimal256 and decimal128 types for varying precisions.

Also provides functions to validate if a given decimal value is within the valid range of the decimal type.

Constants

DECIMAL128_MAX_PRECISION

The maximum precision for DataType::Decimal128 values

DECIMAL128_MAX_SCALE

The maximum scale for DataType::Decimal128 values

DECIMAL256_MAX_PRECISION

The maximum precision for DataType::Decimal256 values

DECIMAL256_MAX_SCALE

The maximum scale for DataType::Decimal256 values

DECIMAL_DEFAULT_SCALE

The default scale for DataType::Decimal128 and DataType::Decimal256 values

MAX_DECIMAL_FOR_EACH_PRECISION

MAX_DECIMAL_FOR_EACH_PRECISION[p-1] holds the maximum i128 value that can be stored in arrow_schema::DataType::Decimal128 value of precision p

MIN_DECIMAL_FOR_EACH_PRECISION

MIN_DECIMAL_FOR_EACH_PRECISION[p-1] holds the minimum i128 value that can be stored in a arrow_schema::DataType::Decimal128 value of precision p
