MathString Vol. 2

A library with functions that compute Strings, to the Digital Style.

Programming Language

Swift 5

Methods

1.- cleanR(n:String)->String:

     This method clean a "number" in form of String, if contains anomalous characters on these.

2.- isNumber(n:String)->Bool:

     Compare byte per byte of the String to check if it's "number".

3.- isSimbol(n:String)->Bool:

     Check if it's "simbol".

4.- absstr(n:String)->String:

     If n contains in first char one negative simbol ('-') or charASCII==45, remove't and then return n.

5.- ShaveStr(n:String)->String:

    Remove the overflow zeros produces in the "Decimal Number" before and after of the dot.

6.- addZeros(n:String)->String:

    Method dependent of another method that transform the "Decimal" to "fraction".

7.- powstr(n:String)->String:

   Returns the raised base to the exponent.

8.- isFrac(n:String)->Bool:

   Compare String to check if it's a "fraction".

9.- residuo(nA:String,nB:String)->String:

   Method COMPLEX and dependent, return the last residue of the division for two numbers, this done for find the MCD for another methods.

10.- MCD(nA:String,nB:String)->String:

   Return the greatest common divisor.

11.- BiggerThan(nA:String,nB:String)->Bool:

   LessThan(nA:String,nB:String)->Bool; Return the boolean band produced after the two numbers comparation.

12.- EvaluateFrac(n:String)->String:

   Method that return the process step by step on form of String.

13.- forstr(nA:String, nB:String)->String:

14.- minusstr(nA:String, nB:String)->String:

15.- plusstr(nA:String, nB:String)->String:

16.-dividestr(nA:String, nB:String)->String:

   Fundamental methods of this Library, since analize the String byte per byte for later evaluate the two "numbers" and return the "result". 

17.- Double(n:String)->String:

   Transform String(int) to String(Double).

18.- lengthCount(n:String)->String:

   Algorithm that calculates the count of the dot, method dependent of Foundamental methods and this is required for these.
