Solve()

Points

• Solves a Mathematical expression in a string
• Solve() supports infinetly large numbers and its +-/* is powered by the respective custom functions (Evaluate, Multiply, Divide).
• Solve() supports functions() and Nesting via [] brackets ( not () )
• Please use function Pow(number, power) in place of ** in equations

Examples

Msgbox,% Solve("1 + 3.5 - [2 * 3] + Antilog(0.3010, ""e"")")

In the above example notice the use of [...] brackets in [2 * 3] . Make sure you use them.
Also, notice the use of double quotes ("") in Antilog(0.3010, ""e"") to escape them.

var = sqrt(4) - [nthroot(17248,3) * antilog(0.3010)] * [892839.2382389 - 89238239.923]
msgbox,% Solve(var)

In the above example, var has the equation.

Evaluate()

Points

• Adds two infinetly large numbers . Supports decimal and negatives.
• Please feed numbers into the function as strings (See below)

number1 = 3292389200000000000382398232309.239230923092302390239230
number2 = 239209239230290239239049349309403434.34930909090
Msgbox,% Evaluate(number1 ,number2)
Msgbox,% Evaluate(number1, "-" . number2)

In the above example, notice the use of = in place of :=
To minus two numbers , look at the 2nd Msgbox "-" . number2

Multiply() and Divide()

Points

• Feed large numbers as Strings
• Better recommended to keep the length param of Divide as 10 which is default. If you want more preciseness you can move it to anything.
• Divide() has smartround which means something like 0.000000003433423 with a length 3 will not give 0.000 but 0.00000000343

Examples

MsgBox,% Divide("434343455677690909087534208967834434444.5656", "8989998989898909090909009909090909090908656454520", 10)
msgbox,% Divide("22","7",100)  ;<--- 100 Decimal places
MsgBox,% Multiply("111111111111111111111111111111111111111111.111","55555555555555555555555555555555555555555555.555")

Roots()

Points

• Gives roots of a polynomial functions
• Can be slow and buggy at times
• Can be inaccurate

Examples

msgbox,% Roots("1,1,1,-3")      ;xcube + xsq + x - 3 = 0
msgbox,% roots("1,1,1,1,-10")   ;x4 +xcube + xsq + x - 10 = 0

UniquePMT(series, Index)

Points

• Gives unique Permuation for a given Index where Index < No of Permutations
• Make Index = All to list down all possible permutations

Examples

msgbox,% UniquePMT("avi,annat,koiaur,aurkoi", "All")  ;no of permutation =  24
msgbox,% UniquePMT("abd", 3)    ;no of permutation = 6

More Notes

• Greater() , fact() , Power() and Prefect() support larger than life numbers . So, feed numbers as strings in them.
• Roots() may have problems . Currently , it seems Roots() has problems with higher deegree polynomials (>3) with larger coffecients (>10). Please dont try to test equations in Roots(). More often than not, it will not be processed.
• FloorG() and ModG() are just like Floor() and Mod() but for larger numbers
• And dont forget to feed numbers as strings . DONT
