Math

Calculate one or more new columns using math functions.

Parameters

Name	Type	Description	Is Optional
math_ops	math_list	List of math operations to generate new columns. For example, ["AGE_COLUMN + 5", "WEIGHT_COLUMN / 100"]
names	value_list	To alias the new columns, provide a list of column names matching the number of math operations.	True

Example

Pull a source Dataset and preview it:

ds = rasgo.get.dataset(id)
print(ds.preview())

	SALESAMOUNT	TAXAMT	DUEDATE
0	3578.27	286.262	2011-01-10 00:00:00
1	3399.99	271.999	2011-01-10 00:00:00
2	3399.99	271.999	2011-01-10 00:00:00

9	3578.27	286.262	2011-01-12 00:00:00

Transform the Dataset and preview the result:

ds2 = ds.math(
    math_ops=['SALESAMOUNT * 10', 'SALESAMOUNT - TAXAMT'],
    names=['SALES10', 'SALESNET'])

ds2.preview()
