I see that someone posted the MRB Constant in the table. Per WP:AB, in clear-cut case, I corrected the year First Described and # of Known Digits. Marvin Ray Burns ( talk) 23:47, 10 May 2009 (UTC)
I doubt the MRB constant should be here (or in List of numbers). Reasons for problems:

Since the Golden ratio is known to billions of digits (at least 17 billion per that article though this article suggests it's actually 100 billion), shouldn't the Square root of 5 also be known to the same billions of digits? After all:

Why is the Rydberg constant on the side of a page titled Mathematical constant? -- Dgroseth ( talk) 00:56, 16 August 2009 (UTC)
Despite the simplicity of this approximation : if we refer to the NIST table the value of Mn/Me = 1838.6836605 and the error being 0.0000011. Now this approximation is approx. is way too far from the real value to be considered serious. The value is 36/((2+2*5^(1/2))^(1/2)-2*Zeta(3))^2 = 1838.691257454... so the error is : 0.007...
the error ratio is about 7000 times the standard error, please refer to the NIST

I was checking some of constants vs Wolfram Alpha, for Sierpiński's constant, WA returns 0.822825249 ... whic is completely different than the article lists here, I have no insight into the discrepancy.-- Billymac00 ( talk) 02:54, 18 April 2011 (UTC)
I find it funny how the table of constants includes i, but it fails to include -1. -1 is more important than i, as it introduces negative numbers, the reciprocal, inverse functions and inverting in general, and its i squared. There is no reason why -1 shouldn't be in the table. — Preceding unsigned comment added by 186.222.145.211 ( talk) 00:55, 29 August 2011 (UTC)

This article is suggesting that there is some universal law that makes the Golden Ratio some sort thing that all possible processes in universe tend toward as they strive for beauty. This is complete nonsense (my edits were reverted). Maneesh ( talk) 17:32, 20 August 2013 (UTC)
Is this article redundant with "List of numbers" and should be merged into it?
Also, if no on merger, on seeing the redundancy of the title with "Constant (mathematics)", I am wondering if there is a problem changing it to "Notable mathematical constants", "Important mathematical constants", or something else?
John W. Nicholson ( talk) 08:14, 27 September 2013 (UTC)
Perhaps all "interesting numbers" should be included?
On a more serious note, number 2 deserves a place as really quite notable - the first (prime) multiple, cardinality of the smallest divided set, the basis of 'even' numbers, the base of binary representation, of duality, the exponent of area, Euler characteristic of any convex polyhedron, and so on. It's just that it seems to be there almost all the time.
A contributor above suggested the inclusion of Tau τ = 2π ; I'd agree. Tau seems to be sidelined on WP; Tau_(2π)#In_popular_culture is almost entirely about π (which has its own page Pi). To be fair, adoption of τ = 2π is something of a minority interest - perhaps consensus considers it to be irrational, but nevertheless it has minor notability.
If i is notable as square root of -1, then so is j = 1/2+i(3^-2)/2, the major complex cube root of 1, solution to x^3=1 {the other roots being 1, & 1/2-i(3^-2)/2}. Of use in engineering, I distantly recall.
Corrigenda: I see in the table, "# of known digits" for 0, 1, i are each shown as "N/A". One might be of the opinion that is incorrect. Also it is unclear to me what the order of that table is supposed to be - after re-sorting, I didn't manage to return to the pristine order except by re-loading. Could we know the rationale? And should imaginary constants be in another table, or come first?
