P: Allow simple maths in number fields.

[FeedbackCommunityMember]

So if I want my canvas to be 43px smaller I can basically type 160-43. Or if I want it to be 2.5x bigger I can do 160x2.5.
Any number field can benefit from this. Very often I have to open the calculator to figure out numbers.

It works in most Adobe products, but very limited. It should support chained calculations such as 3*(15-4)/2.4.

[PECourtejoie]

InDesign, After Effects and Illustrator have that functionnality. Cross-programs users expect the same behavior in Photoshop...

Great suggestion! This would be a nice addition to Photoshop for sure! It would improve functionality of Image Size and Image Rotation as well.

[Marsmanderl]

I even would suggest a little popup calculator for all these number-input-fields. I saw this great little feat in autodesk combustion and inferno. Quite nice - but that should be as an addition to the "inline" calculation.

I can't tell you how much time i wasted on this. In package design when you want to put something on each side of a box you need to rotate the same layer with x°. You can't enter 76+90 to the drop shadow for example. Also in webdesign where you need to be pixel perfect you can't just enter x+73px when you free transform sg. and so on. I mean every app has simple math in input fields and you would think it's called a creative SUIT for a reason but...

Agreed with all of the above; I use Illustrator on a daily basis for sign and poster layouts and frequently make use of this feature in numeric fields. In Photoshop, often used for pixel-perfect web design mockups and UI design, the feature seems to be a no-brainer, and is often a source of frustration for me that it isn't present.

why am I unable to do equations in photoshop width and height boxes like I do in illustrator?
i.e. new document box i can enter 6*72 (as I prefer to work in points) in the width or height box in illustrator and get 432pt. But not in photoshop.........

Could you guys add Logarithmic Resizing? It would save me some work and error when calculating.

[Mathias17]

It's not just that we "expect the same behavior", but that we expect features that make sense and expand the usefulness of the program.

This feature would eliminate the need for a separate calculator program in many cases. That's a plus! Get it? PUN INTENDED

[Mathias17]

Since I discovered the Illy team included the ability to do math in text fields I've always been disappointed by the fact that PS cannot.

This would be a big one, gents!

[daniel_mgs]

Hi! It would be neat if I could just type for example "+4,11" in the "Canvas size" window to add that number to the specific width or height. And that Ps did the math for me. Thanks! /Daniel

[Mathias17]

Hmm, what?

Are you specifying canvas coordinates?

[daniel_mgs]

No. Just trying to add some numbers together.

[Mathias17]

Ah, like a formula then?

Like this: (61+98)+(4+11) ?

I can't make sense of your use of commas otherwise.
I'm no math major though, haha.

[roman1961]

I wonder why no one from Adobe responded to this topic?

[Mathias17]

Nobody on the Photoshop team knows how to do math.

[roman1961]

that's why they should consider adding this feature .. 😛

Are you trying to be funny or are you short on politeness?
The distinction is sometimes difficult in written communication. Edit: At least for me, I guess.

[daniel_mgs]

61,98cm is a distance, just like 62cm, just a little shorter. If you are unfamiliar with the meter system, please look it up at a wiki.

[Mathias17]

Haha, no I agree. Was sarcasm; just poking fun.
I have big respect for the PS team. How could I not. PS is by a landslide my favorite program of all time.

[iMattK]

It would also be nice if actions would record the math modifier instead of the result. For example if I type +5 in the blue of a solid color layer, the action would record that I added five blue, not the result of the addition.

[FeedbackCommunityMember]

That's more of a problem - because you don't know whether the intent was an absolute or relative specification, and the action can be used without the original context. In general, it is much safer to record the absolute unless the field is specified as a percentage.

[Mathias17]

But if there's a "+" or a "-" preceding the value, isn't that explicitly relative? As in, being a modifier of current value, and not a replacement for it?

[FeedbackCommunityMember]

no, because 5+2 != 15+2. Was the intent to get 7, or just to always add 2 -- the application can't know.

[Mathias17]

"5+2 !=" ??? Not following. Also not a math expert. More like a math retard.

I'd be happy if PS allowed simple math in text fields like Illustrator already does.
