Detailed Description

Represents a floating-point number.

Member Function Documentation

create()

cvb.gevserver.FloatNode create	(	str	name,
		Optional[int]	namespace
	)

Creates a new floating-point number node.

The node can be created using only the name with namespace or using the name only and an extra namespace parameter. You must add this node to a node map before most operations are possible.

Parameters

name : str Node name with or without namespace prefix. If the name does not contain a namespace prefix and no namespace is specified separately, cvb.gevserver.NameSpace.Custom is used.

namespace : Optional[int] Namespace to place the node in if not part of the name (see cvb.gevserver.NameSpace).

Returns

cvb.gevserver.FloatNode The requested node.
