Math Functions Not Working?

[JET_Affinity]

Version 1.7.0.188

1. Rectangle Tool: Drag to draw a rectangle.
2. Transform palette: Proportional link off. Key "Sqrt(2)" into W field.
3. Tap Enter key.

Nothing happens.

Interesting. They will work if entered as part of an expression. That is, "*sqrt(2)" works, but "sqrt(2)" doesn't. Both work in Designer 1.6.5.123.

That's because it's an operation on the existing value (i.e. value * sqrt(2)). In theory sqrt(2) should produce a constant number too.

Right. Mainly I tried the expression to prove that sqrt(2) was working at least some of the time. In AD 1.6.5 entering "sqrt(2)" as a value produces 1.414 but in 1.7 it is ignored and the original value is restored.

Ah OK, that's defo a bug then. I thought @JET_Affinity was expecting "value * sqrt(2)" as the result from "sqrt(2)" input.

Yup - looks like a cockroach to me.

Interesting. So sqrt(2) returns a 'constant' value, so independent on the current value of a textbox.

But how does this relate to a textbox, like width or height, set to '50%'? (When entering 50% the %, instead of sqrt(2) ís dependent on the current value since it returns 0.5 * value. Which is actually a pretty great feature btw), so that seems to be a different approach?

Why would it return anything else? The value of sqrt(2) is a constant.

Since 50% represents a proportion rather than an absolute value, it has to be a proportion of something! That ‘something’ can either be another value — e.g. w or h or sqrt(2) — or the current value in the selected input box.
