Proposed Definitions And Examples
cmavo: bi'e (BIhE)
Proposed Definition
Indicates an operator has precedence over unmarked operators. When an operator is prefixed with this cmavo, it becomes automatically of higher precedence than other operators not so prefixed. If more than one operator has a bi'e prefix, grouping is to the right; multiple bi'e prefixes on a single operator are not allowed.
Proposed Keywords
- High priority operator
- Precedence operator
Usage Examples
- li ci su'i vo bi'e pi'i mu du li reci
- 3 + (4 × 5) = 23
Notes
This is distinct from the use of mathematical brackets {vei} and {ve'o}.
cmavo: fu'a (FUhA)
Proposed Definition
Marks the mekso expression as using Reverse Polish (RP) notation. RP notation is always marked by an explicit fu'a at the beginning of the expression. Operators acting in RP are required to have two operands (though {tu'o} and {ge'a} can assist when using unitary and ternary operators respectively).
Proposed Keywords
See also
- {pe'o} Forethought operator flag
- {tu'o} Null operand
- {ge'a} Null operator
Usage Examples
- li fu'a reboi ci su'i du li mu
- (RP) (2 3 +) = 5
- li fu'a reboi ci pi'i voboi mu pi'i su'i du li rexa
- (RP) (2 3 x) (4 5 x) + = 26
- li fu'a ciboi muboi vu'u du li fu'a reboi tu'o va'a
- (RP) (3 5 -) = (RP) (2 null) negative
- li cinoki'oki'o du li fu'a biboi ciboi panoboi ge'a gei
- 30,000,000 = (RP) 8 (3 10 null) exp
Issues
It seems quite arbitrary that operators acting in reverse polish notation are required to have exactly 2 operands. Especially considering that in polish notation, operators are allowed to have as many operands as they like. It does not make semantic sense for all operators (for example the negation operator, used in the example usage above) Though there is a problem in determining which operands belong to which operator, and the solution currently is quite elegant to usage, it lacks symmetry with forethought equivalent and seems contrived. Perhaps {ku'e} could have its use extended from separating groups of operands in forethought mode to doing it in RP mode too.
- Example li fu'a paboi ku'e biboi ciboi panoboi gei su'i du li cinoki'oki'opa
- (RP) 1 (8 3 10 exp) + = 30,000,001
cmavo: jo'i (JOhI)
Proposed Definition
Joins a sequence of simple operands or bracketed full expressions into a vector. A vector may have any number of components. It's corresponding terminator {te'u} is elidable.
Proposed Keywords
See also
- {te'u} Mekso terminator for NAhU, NIhE, MOhE, MAhO, and JOhI
Usage Examples
- li jo'i paboi reboi te'u su'i jo'i ciboi voboi du li jo'i voboi xaboi
- vector (1, 2) + vector (3, 4) = vector (4, 6)
Notes
It is the only member of selma'o JOhI
cmavo: ku'e (KUhE)
Proposed Definition
This is the elidable terminator of operators when they are acting in forethought mode. It serves to distinguish where the operands of one operator end and another begin.
Proposed Keywords
- Forethought operator terminator
See Also
- {pe'o} Forethought operator flag
Usage Examples
- li py. su'i va'a ny. ku'e su'i zy du li xy.
- p + (negative n) + z = x
cmavo: ma'o (MAhO)
This flag converts letteral string or other mathematical expression (mex) operand into a mex operator. Its elidable terminator is {te'u}.
Proposed Keywords
Usage Examples
- li zy du li ma'o fy.boi xy.
- z = f(x)
Notes
The CLL has the following observation: There is a potential semantic ambiguity in ma'o fy. [te'u] if fy. is already in use as a variable: it comes to mean "the function whose value is always 'f' ". However, mathematicians do not normally use the same lerfu words or strings as both functions and variables, so this case should not arise in practice.
