Euler’s constant


Recommended Posts

I seem to have trouble with Euler's constant. I am certain that I'm just have brain fart. But in my mind I should be able to access that value as constant equal to 2.71828182845904. 

I can use the other constants like, pi, phi and root2 directly in the Transform panel by setting the W as pi, phi or root2. But not e. It is bold and red as if it is unknown or invalid. 

Is this expected, or I am confusing Euler's constant with something else? 😂 

I would it the following.

pi = 3.141592653589793
phi = 1.618033988749894
root2 = 1.41421
e = 2.71828182845904

I have no answer for you but please see the xkcd comic. Maybe get a laugh.

I have never mastered color management, period, so I cannot help with that.

From V1 Help

Mathematical constants

For general use throughout the user interface.

Input Constant
pi, π For Pi
phi, gr, φ For golden ratio
root2, rad, rt For Pythagoras’s constant
e Euler’s constant

 

e to me is Euler's number ie 2.7 and a bit, base of natural logs

Euler's constant is 0.57721 and a bit so I'm not sure what the help means

Whatever, e doesn't work whereas pi, phi and root2 do so I suspect it's a Serif fart

That's right!

The help probably means the Napier's constant (Euler number), e = epsilon, since the Euler-Mascheroni constant = gamma = gamma. - In Affinity e 's usage is probably more meant for APh equation filters, or they have forgotten to set it up globally for input fields.

Also weird that w=width and h=height aren't available when creating a grid in the Grid and Snapping Axis window. 

I am not sure I understand what you mean. That spacing would "w" represent the width of, the entire document or something else?

Yes, would be nice as formula, e.g. w/8

in some instances, you may need to use sw (spread width) instead of w, but for grid no constants/ variables are allowed

My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you. Otherwise I’m a fine person which respects you and everyone and wants to be respected.
