Scalar

class lsst.analysis.tools.Scalar

Bases: Number, 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.

newbyteorder(new_order='S', /)

Return a new dtype with a different byte order.

Changes are also made in all fields and sub-arrays of the data type.

The new_order code can be any from the following:

• ‘S’ - swap dtype from current to opposite endian

• {‘<’, ‘little’} - little endian

• {‘>’, ‘big’} - big endian

• ‘=’ - native order

• {‘|’, ‘I’} - ignore (no change to byte order)

Parameters:

new_orderstr, optional

Byte order to force; a value from the byte order specifications above. The default value (‘S’) results in swapping the current byte order.

Returns:

new_dtypedtype

New dtype object with the given change to the byte order.
