compute_arithmetics only.Expand description
Defines the arithmetic kernels for Decimal PrimitiveArrays. The
Decimal type specifies the
precision and scale parameters. These affect the arithmetic operations and
need to be considered while doing operations with Decimal numbers.
Functions
Adaptive addition of two decimal primitive arrays with different precision and scale. If the precision and scale is different, then the smallest scale and precision is adjusted to the largest precision and scale. If during the addition one of the results is larger than the max possible value, the result precision is changed to the precision of the max value
Adaptive division of two decimal primitive arrays with different precision and scale. If the precision and scale is different, then the smallest scale and precision is adjusted to the largest precision and scale. If during the division one of the results is larger than the max possible value, the result precision is changed to the precision of the max value. The function panics when divided by zero.
Adaptive multiplication of two decimal primitive arrays with different precision and scale. If the precision and scale is different, then the smallest scale and precision is adjusted to the largest precision and scale. If during the multiplication one of the results is larger than the max possible value, the result precision is changed to the precision of the max value
Adaptive subtract of two decimal primitive arrays with different precision and scale. If the precision and scale is different, then the smallest scale and precision is adjusted to the largest precision and scale. If during the addition one of the results is smaller than the min possible value, the result precision is changed to the precision of the min value
Adds two decimal PrimitiveArray with the same precision and scale.
Checked addition of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the sum is larger than the possible number with the selected precision (overflowing), then the validity for that index is changed to None
Checked division of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the divisor is zero, then the validity for that index is changed to None
Checked multiplication of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the mul is larger than the possible number with the selected precision (overflowing), then the validity for that index is changed to None
Checked subtract of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the sub is larger than the possible number with the selected precision (overflowing), then the validity for that index is changed to None
Divide two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. This function panics if the dividend is divided by 0 or None. This function also panics if the division produces a number larger than the possible number for the array precision.
Multiply a decimal PrimitiveArray with a PrimitiveScalar with the same precision and scale. If
the precision and scale is different, then an InvalidArgumentError is
returned. This function panics if the multiplied numbers result in a number
larger than the possible number for the selected precision.
Multiply two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. This function panics if the multiplied numbers result in a number larger than the possible number for the selected precision.
Multiply a decimal PrimitiveArray with a PrimitiveScalar with the same precision and scale. If
the precision and scale is different, then an InvalidArgumentError is
returned. This function panics if the multiplied numbers result in a number
larger than the possible number for the selected precision.
Saturated addition of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the sum is larger than the possible number with the selected precision then the resulted number in the arrow array is the maximum number for the selected precision.
Saturated division of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the division is larger than the possible number with the selected precision then the resulted number in the arrow array is the maximum number for the selected precision. The function panics if divided by zero.
Saturated multiplication of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the multiplication is larger than the possible number with the selected precision then the resulted number in the arrow array is the maximum number for the selected precision.
Saturated subtraction of two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. If the result from the sum is smaller than the possible number with the selected precision then the resulted number in the arrow array is the minimum number for the selected precision.
Subtract two decimal primitive arrays with the same precision and scale. If the precision and scale is different, then an InvalidArgumentError is returned. This function panics if the subtracted numbers result in a number smaller than the possible number for the selected precision.
