relationalai.std.math
#degrees(radians: Number | Producer) -> Expression
Converts radians to degrees. Must be called in a rule or query context.
Parameters#
Name | Type | Description |
---|---|---|
radians | Number or Producer | The number of radians to convert to degrees. |
Returns#
An Expression
object that produces float
values.
Example#
degrees()
works with both numeric producers and Python number objects:
#import relationalai as rai
from relationalai.std import alias
from relationalai.std.math import degrees
# Create a model named "people" with a Person type.
model = rai.Model("people")
Person = model.Type("Person")
# Add a person to the model.
with model.rule():
Person.add(name="Alice", age=30)
# degrees() works with numeric producers, such as a person's age property.
with model.query() as select:
person = Person()
response = select(person.name, alias(degrees(person.age), "degrees_age"))
print(response.results)
# Output:
# name degrees_age
# 0 Alice 1718.873385
# degrees() also works with Python number objects.
with model.query() as select:
response = select(degrees(3.141593))
print(response.results)
# Output:
# v
# 0 180.00002
