We have Add, Subtract, Multiply, Divide currently.
It would be great to have modulus to get the remainder, this addition shouldn’t be difficult.
It would be great to round variables with various rounding methods such as floor, ceiling, etc.
It would be great to expand the amount of characters allowed for number input which is currently only 6, this currently limits usage of scientific notation such as “1.34e-12” and long decimal numbers.
Add a square root or even better a “Power” Action that allows you to apply the power of something to a variable. If you do this, then there won’t even need to be a square root action, since you can do the x^0.5 as a sqrt.
Finally, add trigonometric functions such as sine, cosine and tangent, but there aren’t many practical applications for this yet.
