Fract Node
Access: Nodes > Math > Fract
The Fract node calculates the fractional part (frac) of an input value by subtracting the floor 
of the input value from the input value. The Fract node then outputs the result which is only the decimal place remainder of the input.
| Input | Output |
| 5.385, 0.164, 3.065, 1.0 | 0.385, 0.164, 0.065, 0.0 |
| 267.19, 105.096, 25.483, 1.0 | 0.19, 0.096, 0.483, 0.0 |
| 3.0, 7.0, 4.0, 1.0 | 0.0, 0.0, 0.0, 0.0 |
Note: For more information on the frac calculation, see here for an explanation provided by MathWorks. For information about the floor calculation, see Floor node.
The Fract node can be used in multiple ways, one workflow is to use the node to determine where a certain UV coordinate is from within a patch. Using a Fract node after a UV will output just its position within the patch.
Another workflow is to use the Fract node to repeat a part of your texture that's looked up by UV coordinates across each patch. For example, using a Fract node before a Gradient node to repeat the gradient across each patch.
