NumberFlow, float nodes
These nodes provide a collection of floatingpoint functions. The example images use U as the first
and V as the second input.
 Add

Adds two float together.
 Add Add
 Adds three floats together. This is slightly faster and more convenient than using two Add nodes.
 Subtract

Subtracts the second float from the first.
 Multiply

Multiplies two floats together.
 Divide

Divides the first float by the second. It's typically faster to use multiply instead.
 Modulo

Computes the first float modulo the second.
 Absolute

Takes the absolute value of a float. The example image shows the absolute of (U  V).
 Square

Squares a float.
 Cube

Cubes a float.
 Square Root

Computes the square root of a float.
 From Int
 Converts an int to a float.
 Curve
 Evaluates a point on a curve.
 Lerp

Linearly interpolates between two floats based on a third. The example image interpolates
between U and V based on (UV center distance × 2).
With 1
These are convenient nodes for addition, subtraction, and division with the number one.
 + 1

Adds one to a float.
  1

Subtracts one to a float.
 1 

Subtracts a float from one.
 1 %

Divides one by a float.
Relative
 Highest

Takes the highest of two floats.
 Lowest

Takes the lowest of two floats.
 Average

Takes the average of two floats.
Range
The example images use (U × 3  1) as input.
 Clamp 01

Clamps a float to the 0–1 range. Clamping has no effect for the example image,
as values outside of the color range are clamped already.
 Loop 01

Loops a float over the 0–1 range.
 PingPong 01

Pingpongs a float over the 0–1 range.
Trigonometry
The example images use (U × 10) as input and are transformed from the 1–1 range to the
0–1 range.
 Cosine

Computes the cosine of a float.
 Sine

Computes the sine of a float.
 Sinusoid

Converts a float to a sine wave with a configurable frequency and offset. This is
often more convenient that using sine or cosine directly.
The example image uses V as the frequency and an offset of 0.
