Floor Node
Access: Nodes > Math > Floor
The Floor node rounds down values to the nearest whole number or integer.
Note: The Floor node is similar to the Ceil node operation, except instead of rounding up to the nearest whole number, Floor rounds down. For more information, see the Ceil node.
Input  Output 
3.75, 5.08, 2.49, 1.0  3, 5, 2, 1 
5.0, 6.5, 7.2, 1.0  5, 6, 7, 1 
0.0, 0.3, 0.7, 0.0  0, 0, 0, 0 
Floor Node Inputs
Input 
The input values to be rounded down to the nearest integer.

Floor Node Outputs
Output 
The input after rounding down to the nearest whole number.

Floor Node Workflow Example
The Floor node can be used to create a simple posterize effect from a texture color input. To define the number of levels in the posterize effect, you can use the Multiply and Divide nodes, in the following way, where the Multiply and Divide B inputs are the number of levels you would like in the posterize effect:
Workflow to Create a Posterize Effect using a Floor Node 
Note: The Floor node produces a similar posterize effect to the Ceil node but because it rounds the input values down, the resulting colors will appear darker.
