Resizing

[scgreentea]

Hi all,
I can resize a selection by Phi,
It is ok to type XX*Phi* phi* Phi (for Phi*3) but when wanting to multiply by higher numbers like Phi*30 it gets a bit tedious trying that many Phi's, is there a better short cut way to entering this into the transformation box?
Thanks in advance.
Shane.

Isn't that phi to the third power, not phi times 3?

• Affinity expressions for field input!
• 3 ^ 5
• phi ^ 3
• phi ^ 30
• 1.618 ^ 3
• 1.618 ^ 30
• Golden ratio (phi)

Thanks you for the replies.
As i am not at all mathematically minded thank you for explaining to the power of XX to me. 
Starting with a 10mmx10mm square I did try phi^3 (if i typed in correctly) the resulting square 4236.1mm this is way too big in relation to the 10mmx10mm , with the same 10mmx10mm square and typing in phi*phi*phi results in a square of 42.4 mm (this is closer to the ratio i am looking for). Again i am not mathematically minded and what i am asking may be mathematically incorrect, but if there is a better way to typing it in for higher ratio numbers i would be most grateful.

I am not really clear what it is that you are resizing. I created a 10mm square and resized it using *=phi^3 (phi cubed) and the resulting size was 42.4mm square, what I would expect.

Thanks for your reply.
That is the result i want but not the result i am getting😕
and now for some reason phi^3 is not resizing at all.
Just in case i am typing it in wrong would you mind typing exactly what you typed in than i should get the same result.
thanks again

John already did that in his previous reply:

So try entering *=phi^3 & see what you get. The way this expression works is the first 2 characters (*=) stand for the current value (width or height, for example) & phi^3 is PHI cubed (PHI to the third power, or approximately 4.24). Thus, for a 10 mm dimensional value, the result is 10 mm times 4.24, or 42.4 mm.

Or rather, those first two characters say ‘multiply the current value by’. In the same way, you could type /= if you wanted to divide, += if you wanted to add, or -= if you wanted to subtract.

Thanks for all the help
got it to work

Thanks for the correction. I have never really gotten used to the idea of using the = sign as a reference to the current value so I usually try to use something more natural to me like w*phi^3 ... but that does not seem to be working reliably in the 1.9.1 Mac versions.

Or how C/C++ or C#/Java etc. programmers would often abbreviate such things in their code, now you know where the origins come from ... ...

• x = x * n   --->   x *= n
• x = x / n   --->   x /=n
• x = x + n  --->   x += n
• x = x - n   --->   x -= n
• x = x + 1  --->   x++
• x = x - 1   --->   x--
• ... and so on ...
• see Operators in C and C++  or
• see C/C++ language operators etc.

At least to me it still seems like a bit of an odd choice in the context of the Affinity apps (because the target audience probably includes relatively few programmers).

Be that as it may, am I the only one seeing phi showing up in red in the transform panel as if it is a disallowed expression, & forms like w*phi^3 being ignored completely while w*(phi^3) or just phi^3 works as expected? (Using the Mac 1.9.1 versions.)

No, I see it here as well.
