- pai
- digit/number: pi (approximately 3.1416...); the constant defined by the ratio of the circumference to the diameter of all circles.

- ne'o'a
- mekso ternary operator: the generalized incomplete (factorial-extending) Pi function; for input (X
_{1, X}this word outputs the definite integral of t^X_{1 e^-t}with respect to t from X_{2}to X_{3}(see notes for default values). - gei'i'e
*(exp!)* - mekso unary operator: converts a string of digits which includes {pi} to the same string of digits without {pi}; if {pi} is not present in the original/input string, the output is identical
- pi'au
*(exp!)* - digit/number: pi (approximately 3.1416...); the constant defined by the ratio of the circumference to the diameter of all circles.
- plankexu
- x
_{1}is the elementary unit (quantum) of angular momentum/half of Planck's reduced constant [id est: hbar/2 = h/(4 pi)] expressed in units x_{2}(default: unitless/dimensionless and so that it is equal to 1) in paradigm/system/metaphysics/universe x_{3}(default: this, our actual, physical universe) - stefanboltsemasi
- x
_{1}is the black-body Stefan-Boltzmann sigma_{SB}constant [approximately equal to: 5.670373(21)×10^{(−8)}W/(m^{2}×K^{4})], expressed in units x_{2}(default: unitless/dimensionless and equal to pi^{2 / 480}) in paradigm/system/metaphysics/universe x_{3}(default: this, our actual, physical universe)

- bi'oi'au
- digit/number: interval/range indicator for significant digits (determined by lesser endpoint).
- mi'i'au
- digit/number: interval/range indicator for significant digits (determined by midpoint).
- ne'o'au
- mekso quaternary operator: polygamma function; for input X
_{1, X}, outputs the (-X_{2)}th derivative of Log(ne'o'a(X_{1, X})) with respect to X_{1}. - pisu'osoi'ai
*(comp!)* - digit/number: at least almost-all of; at least almost-certain; 100%.
- pizau'u
*(comp!)* - arbitrarily much of, arbitrarily close to 1, an arbitrarily large proper fraction/percentage of
- fatysaclu
- x
_{1}(me'o) is the p-adic representation of number x_{2}in base x_{3}. - temjudri
- x
_{1}is a point on time axis, of event/state x_{2}, in system x_{3}. - gau'a
*(exp!)* - mekso (no-more-than-4-ary) operator: Gaussian function f(x, a, b, c) = c e
^{-((x-a)}. - ju'au
*(exp!)* - semi-mathematical binary operator: named number base operator/interpreter
- ka'o'ei
*(exp!)* - imaginary i, comma - spherical coordinates: first coordinate gives magnitude (complex modulus/radius) of the number, the second number gives the angle from the positive real axis measured counterclockwise toward the 'positive' imaginary axis (default: in the primary branch/Arg) as measured in some units (which that number should contain; the contextless default will suppose radians); the angle is not normalized.
- ne'oi
*(exp!)* - unary operator: primorial a#
- si'ei
*(exp!)* - numeric suffix: indicates that the number refers to portionality instead of cardinality
- te'i
*(exp!)* - at a point on time axis
- xo'ei
*(exp!)* - unary mekso operator: produces a string of n consecutive "xo'e"'s, treated as digits (concatenated into a single string of digits)
- xaudbo
- x
_{1}is \sqrt(A) [decimal: 1×10^{+(1/2)}] of x_{2}in dimension/aspect x_{3}(default is units).
