**Nearest Integer**[edit]

**Node Description & Purpose: **

The Nearest integer node takes the Input value and outputs the nearest integer, or whole number. It rounds decimal values less than .5 downward and decimal values of .5 and greater upward. For example:

An input of 2.2 will become 2.0

An input of 2.5 will become 3.0

An input of 2.9 will become 3.0

An input of 5.0 will become 5.0

Despite it not being obvious from the node name, the Nearest integer node is essentially a scalar node.

Due to way floating point numbers are represented, the scalar output may not always be an exact integer.**Node Type: ** Function**Settings: **

This node has no other settings apart from the Input node.

A scalar is a single number. 1, 200.45, -45, -0.2 are all examples of scalar values.

A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.
