# More Math
|
|
|
|
Adds math nodes for numbers and types which do not need it. I got inspired by was_extras node.
|
|
|
|
#WARNING This node is not compatible to ComfyUI-Impact-Pack which forces older antlr version.
|
|
|
|
## Quickstart
|
|
|
|
1. Install [ComfyUI](https://docs.comfy.org/get_started).
|
|
1. Clone this repository into `ComfyUI/custom_nodes`.
|
|
1. Restart ComfyUI.
|
|
|
|
You can also get the node from comfy manager under the name of More math.
|

# Features
|
|
|
|
- expression parsing with support for functions and variables:
|
|
- functions:
|
|
- run expressions on both components of CONDITIONING (not that I know what they do), LATENT, IMAGE, NOISE and FLOAT
|
|
- math operators (binary and unary +,- and ^,*,/,%)
|
|
- boolean operators (false = 0.0; true = 1.0) (<,<=,>,>=,==,!=)
|
|
- sin, cos, tan
|
|
- asin, acos, atan (can produce NaN outside range -1...1)
|
|
- atan2 (x,y)
|
|
- sinh, cosh, tanh
|
|
- asinh, acosh, atanh (can produce NaN outside range -1...1)
|
|
- abs, sqrt (produces NaN on negative numbers), ln (log with base e), log (base 10), exp, pow
|
|
- smin, tmin, smax, tmax, tnorm, snorm (norm and t prefixed are not applicable on float math node)
|
|
- s prefixed return one number
|
|
- t prefixed work element-wise
|
|
- floor, ceil, round, gamma, clamp, sigm (sigmoid)
|
|
- angle (audio node)
|
|
- variables
|
|
- a, b, c, d : inputs of type based on node
|
|
- w, x, y, z : each node allows use of 4 additional floats
|
|
- W : Width of tensor - does not work on FLOAT and CONDITIONING
|
|
- H : Height of tensor - does not work on FLOAT and CONDITIONING
|
|
- C : Channel of tensor - used as color chanel in IMAGE or as information channel in others. does not work on FLOAT and CONDITIONING
|
|
- B : Batch - does not work on FLOAT and CONDITIONING
|
|
- X : X position in tensor - does not work on FLOAT and CONDITIONING
|
|
- Y : Y position in tensor - does not work on FLOAT and CONDITIONING
|
|
- I : Tensor used to initalise sampler before noise injection - usually zeroed out and generated by Empty Latent Image node - Exclusive for NOISE
|
|
- use constant e and pi
