-------------------------------------
Summary: Add DIV and IEEE_DIVIDE functions (enabled in BigQuery
library)
Key: CALCITE-5983
URL: https://issues.apache.org/jira/browse/CALCITE-5983
Project: Calcite
Issue Type: Improvement
Reporter: Tanner Clary
Assignee: Tanner Clary
BigQuery offers the DIV function
([docs|https://cloud.google.com/bigquery/docs/reference/standard-sql/mathematical_functions#div])
and the IEEE_DIVIDE function
([docs|https://cloud.google.com/bigquery/docs/reference/standard-sql/mathematical_functions#ieee_divide]).
The {{DIV(x, y)}} function returns the result of integer division of X by Y.
Division by zero returns an error. Division by -1 may overflow.
The {{IEEE_DIVIDE(x, y)}} function divides X by Y; this function never fails.
Returns Double. Unlike the division operator (/), this function does not
generate errors for division by zero or overflow.
{{DIV}} examples:
1. {{DIV(20, 4)}} should return {{5}}.
2. {{DIV(2.5, 1)}} should return {{2}} because the result is floored to the
nearest integer.
3. {{DIV(20, 0)}} should throw an error like: {{Division by zero}}.
{{IEEE_DIVIDE}} examples:
1. {{DIV(20, 4)}} should return {{5.0}}.
2. {{DIV(20, 0)}} should return {{Infinity}}.
3. {{DIV(0, 0)}} should return {{NaN}}.
