__floordiv__()#
relationalai.Producer
#Producer.__floordiv__(other: Any) -> Expression
Returns an Expression
that produces the quotient of the Producer
values and other
, rounded towards negative infinity.
The type of the result is the same as the type of the producer’s values.
.__floordiv__()
is called when the //
operator is used.
Parameters#
Name | Type | Description |
---|---|---|
other | Any | The denominator of the floor division operation. |
Returns#
An Expression
object.
Example#
#import relationalai as rai
model = rai.Model("people")
Person = model.Type("Person")
with model.rule():
Person.add(name="Fred", age=39, account_balance=-123.45)
Person.add(name="Wilma", age=36, account_balance=123.45)
with model.query() as select:
person = Person()
half_age = person.age // 2
response = select(person.name, half_age)
print(response.results)
# Output:
# name result
# 0 Fred 19
# 1 Wilma 18
The type of the result is the same as the type of the numerator in the division.
Since the age
property is an integer, the result is also an integer.
For negative numbers, the result is rounded towards negative infinity:
#with model.query() as select:
person = Person()
response = select(person.account_balance // 2)
print(response.results)
# Output:
# result
# 0 -62.0
# 1 61.0
