Digit/number: pi (denoted "π"; approximately 3.1416...); the constant defined by the ratio of the circumference to the diameter of all circles in Euclidean space.
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
mekso ternary operator: the generalized incomplete (factorial-extending) Pi function; for input (X1, X this word outputs the definite integral of t^X1 e^-t with respect to t from X2 to X3 (see notes for default values).
x1 is the elementary unit (quantum) of angular momentum/half of Planck's reduced constant [id est: hbar/2 = h/(4 pi)] expressed in units x2 (default: unitless/dimensionless and so that it is equal to 1) in paradigm/system/metaphysics/universe x3 (default: this, our actual, physical universe)
x1 is the black-body Stefan-Boltzmann sigmaSB constant [approximately equal to: 5.670373(21)×10(−8) W/(m2×K4)], expressed in units x2 (default: unitless/dimensionless and equal to pi2 / 480) in paradigm/system/metaphysics/universe x3 (default: this, our actual, physical universe)
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.
mathematical quinary operator; big operator: left sequence notation/converter - operator a, sequence b defined as a function on index/argument/variable/parameter c, in set d, under ordering e
