I have tried to use forminator (1.22.1 – free version) plug-in for a mathematical model, but I am lacking basic mathematical transformations like logarithm and power. What is the most efficient, free and mathematically versatile WordPress workflow to run calculations (one output float) based on one input float?
Ideally containing (necessity in descending order):

• Input field with unit
• Output field with unit
• Display of mathematical formula
• Graphical plot of function
