Mathematical functions and operators.

Arithmetic Operators¶

The following native arithmetic operators are available directly on any of the dsl.Operable instances:

Examples

>>> ETL = Student.select(Student.surname, Student.score * Student.level * 0.32)

Mathematical Functions¶

class forml.io.dsl.function.Abs(arg: dsl.Operable)[source]¶

Return the absolute value.

Examples

>>> ETL = Student.select(Student.surname, function.Abs(Student.level - 5))

class forml.io.dsl.function.Ceil(arg: dsl.Operable)[source]¶

Return the value rounded up to the nearest integer.

Examples

>>> ETL = Student.select(Student.surname, function.Ceil(Student.score))

class forml.io.dsl.function.Floor(arg: dsl.Operable)[source]¶

Return the value rounded down to the nearest integer.

Examples

>>> ETL = Student.select(Student.surname, function.Floor(Student.score))
