## tupleIntDiv
|
||||
|
||||
Does integer division of a tuple of numerators and a tuple of denominators, and returns a tuple of the quotients.
|
||||
|
||||
**Syntax**
|
||||
|
||||
```sql
|
||||
tupleIntDiv(tuple_num, tuple_div)
|
||||
```
|
||||
|
||||
**Parameters**
|
||||
|
||||
- `tuple_num`: Tuple of numerator values. [Tuple](../data-types/tuple) of numeric type.
|
||||
- `tuple_div`: Tuple of divisor values. [Tuple](../data-types/tuple) of numeric type.
|
||||
|
||||
**Returned value**
|
||||
|
||||
- Tuple of the quotients of `tuple_num` and `tuple_div`. [Tuple](../data-types/tuple) of integer values.
|
||||
|
||||
**Implementation details**
|
||||
|
||||
- If either `tuple_num` or `tuple_div` contain non-integer values then the result is calculated by rounding to the nearest integer for each non-integer numerator or divisor.
|
||||
- An error will be thrown for division by 0.
|
||||
|
||||
**Examples**
|
||||
|
||||
Query:
|
||||
|
||||
``` sql
|
||||
SELECT tupleIntDiv((15, 10, 5), (5, 5, 5));
|
||||
```
|
||||
|
||||
Result:

||||

||||

|

## tupleIntDivOrZero
|
||||
|
||||
Like [tupleIntDiv](#tupleintdiv) it does integer division of a tuple of numerators and a tuple of denominators, and returns a tuple of the quotients. It does not throw an error for 0 divisors, but rather returns the quotient as 0.
|
||||
|
||||
**Syntax**
|
||||
|
||||
```sql
|
||||
tupleIntDivOrZero(tuple_num, tuple_div)
|
||||
```

||||
|
||||
- `tuple_num`: Tuple of numerator values. [Tuple](../data-types/tuple) of numeric type.
|
||||
- `tuple_div`: Tuple of divisor values. [Tuple](../data-types/tuple) of numeric type.
|
||||
|
||||
**Returned value**
|
||||
|
||||
- Tuple of the quotients of `tuple_num` and `tuple_div`. [Tuple](../data-types/tuple) of integer values.
|
||||
- Returns 0 for quotients where the divisor is 0.
|
||||
|
||||
**Implementation details**
|
||||
|
||||
- If either `tuple_num` or `tuple_div` contain non-integer values then the result is calculated by rounding to the nearest integer for each non-integer numerator or divisor as in [tupleIntDiv](#tupleintdiv).

||||
|
||||
**Examples**

||||
Query:

|
||||
|
||||
**Returned value**
|
||||
|
||||
- Tuple of the quotients of `tuple_num` and `div`. [Tuple](../data-types/tuple) of integer values.
