Description

A simple C++ API to translate normal string numbers into Scientific Notation type.

It's in order to provide an example for the C++ beginners,and for those who haven't wrote a Git Repository as a documentional example.

Usage

Clone the entire repository,and simplely include the Scientific_Notation.h & Scientifc_Notation.cpp files into your projects/source files.

Use SN_NUMBER foo(str) to declare a scientific number class,use foo.SN_Producer() to produce a scientific notation digits string.

Example

std::string NumStr = "1024.96";
SN_NUMBER MyNum1(NumStr), MyNum2("123456");
std::cout << "MyNum1:" << MyNum1 << std::endl;
std::cout << "MyNum2:" << MyNum2 <<"Number of digits: "<< MyNum2.NDIGIT() << std::endl;
SN_NUMBER MyNum3("12a3445");

The Outputs would be:

MyNum1:1.02496E3
MyNum2:1.23456E5 Number of digits:6
Error info: Some of the inputs is not digit.

Document

Class' inside functions declared are listed by:

SN_NUMBER(std:: string SN_NUMSTR, NTYPE type)

Construct a SN_NUMBER class using string,differs the explaination type.

The default type is SN_NUMBER::NTYPE_EXP,which looks like:

1.345789E3

For example:

SN_NUMBER("3145.92657");
SN_NUMBER(str,SN_NUMBER::NTYPE_TENS);
SN_NUMBER("3145.92657",SN_NUMBER::NTYPE_EXP);

DOTP()

Rturns an interger that shows the dot's position in the former number

NDIGIT()

Returns an interger that shows the length of number.

DIGIT()

Returns an interger that shows the digits of former number's interger part.

Support

Get easy to create issues if you find a bug,pull requests are welcomed.

But,seriously,even this is a repository is for beginners,C++ basics are stupid questions,please turns to C++ guidebooks.
