Detailed Description

It's a Exponented under a square root The Exponented can be either numeric or literal.

Definition at line 1303 of file base_calculus.py.

Constructor & Destructor Documentation

def core.base_calculus.SquareRoot.__init__	(	self,
		arg,
		options
	)

Constructor.

Warning:: Might raise an UncompatibleType exception.

Parameters:

arg	Exponented\|(sign, Exponented) The given Exponented will be "embedded" in the SquareRoot
options	: copy='yes' can be used to produce a copy of another SquareRoot. If not used, the other SquareRoot will get embedded in a new SquareRoot.

Returns:: One instance of SquareRoot
