Module arrow_data::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
