Much thanks for the comments/edits on en:talk:Numbers. It certainly needs some inspection though. Regards, -Stevertigo 28. apr 2005 kl. 02:31 (CEST)

Thank you for the translation. It is much appreciated. Renier


[redigér] Suggestion for new template:Numbers

Left: before Right: My suggestion

The changes I've made are the following:

  • for naturals, I specified 1/2, 1/3,2/3,1/4 etc. according to "normal" notation
  • I've tried to arrange the list of elementary better according to quantity. I´m not sure about the right positioning of computable and split-complex numbers
  • I removed i and Tr from the real numbers - I don't think they belong there.
  • I removed a dual entry/link for real numbers (reals)
  • I added the imaginary numbers to the list (probably should have been placed after "real numbers" :-(
  • I added the transfinite numbers to the list
  • pi, i, and e were moved to the last section. They are the basic symbols of geometry, complex numbers, and logarithms, respectively (and elements of the famous Euler equation)
  • I tried to find a proper heading for the last section. Improvements may be found.
  • and, finally, a small amount of editing


Number systems in mathematics.
Elementary

\mathbb{N} Naturals {0,1,2,3..}
\mathbb{P} Primes ⊂\mathbb{N}, \mathbb{P}=\mathbb{N}x:{1,x}
\mathbb{Z} Integers {..-1,0,1,..}
\mathbb{D} Decimals (.454, etc.)
\mathbb{Q} Rationals { \mathbb{Z}, 1/2 , 1/3 , 2/3, 1/4 etc.}
Irrational numbers
Constructibles
Imaginary numbers
\mathbb{R} Real numbers {\mathbb{Z} , \mathbb{Q}}
\mathbb{C} Complex numbers {\mathbb{R} , \mathrm{i}},
Algebraic numbers
\mathbb{Tr}Transcendentals
Transfinite numbers
Computable numbers
R1,1 Split-complex

Complex extensions

Bicomplex
Hypercomplex
{\mathbb{R},i,j,k} Quaternions ~i2=j2=k2=ijk=-1
Octonions
Sedenions
Superreal
Hyperreal
Surreal

Types of numbers / special numbers

Nominal
Ordinal size, position {n}
Cardinal {\aleph_1, \aleph_2, \aleph_3, \cdots}
p-adic's
Integer sequences
Math constants
Large numbers
i Imaginary unit ≈/= \sqrt{-1}
π Pi = {3.14159 26535 ...}
e "e" (constant) ≈ 2.71828 (≠ \mathbb{Q})
∞ Infinity
