Scalar¶

class lsst.analysis.tools.Scalar¶

Bases: numbers.Number, numpy.number

This is an interface only class, and is intended to abstract around all the various types of numbers used in Python.

This has been tried many times with various levels of success in python, and this is another attempt. However, as this class is only intended as an interface, and not something concrete to use it works.

Users should not directly instantiate from this class, instead they should use a built in python number type, or a numpy number.
