NumberFlow, float nodes

These nodes provide a collection of floating-point functions. The example images use U as the first and V as the second input.
Add
add
Adds two float together.
Add Add
Adds three floats together. This is slightly faster and more convenient than using two Add nodes.
Subtract
subtract
Subtracts the second float from the first.
Multiply
multiply
Multiplies two floats together.
Divide
divide
Divides the first float by the second. It's typically faster to use multiply instead.
Modulo
modulo
Computes the first float modulo the second.
Absolute
absolute
Takes the absolute value of a float. The example image shows the absolute of (U - V).
Square
square
Squares a float.
Cube
cube
Cubes a float.
Square Root
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
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
highest
Takes the highest of two floats.
Lowest
lowest
Takes the lowest of two floats.
Average
average
Takes the average of two floats.

Range

The example images use (U × 3 - 1) as input.
Clamp 01
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
loop 01
Loops a float over the 0–1 range.
PingPong 01
pingpong 01
Ping-pongs 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
cosine
Computes the cosine of a float.
Sine
sine
Computes the sine of a float.
Sinusoid
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.
