NOTE: If [s] is marked as a static method, it can be used without instantiating an object.

 

Number. Format (Format)

Format the number with the specified format (region setting is irrelevant ).

 

Number. localeformat (Format)

Format the number with the specified format (related to region settings ).

 

Supported formats

1. P: Convert the number into a percentage string (e.g.:-1,234.56%)
2. D: Convert the number into a decimal string without a comma separator (e.g.:-1234.56)
3. C: convert a number into a currency amount (e.g.: (Jun 1,234.56 ))
4. N: concatenate digits into commas (,) to separate them (-D, DDD, DDD... ") Form (e.g.:-1,234.56)

 

[S] Number. parselocale (value)

Parses the local number represented by a string into the corresponding number type. Use SYS. cultureinfo. currentculture to obtain the current region attribute.

 

[S]Number. parseinvariant (value)

Parses the local number represented by a string into the corresponding floating point number type. Value can contain commas (,) or plus or minus (+.

 
VaRA =NewNumber ();
 

 
A = number. parseinvariant ("4");
 

 
VaRB =NewNumber (2 );
 

 
VaRC = number. parseinvariant ("1.53") + A + B;
 

 
// C = 7.53
 

 

Error-related methods

2. [S]Error. Argument: Creates a sys. argumentexception type exception based on the specified exception information and invalid parameters.
4. [S]Error. argumentnull: Create a sys. argumentnullexception type exception based on the specified exception information and the null parameter.
6. [S]Error. argumenttype: Create a sys. argumenttypeexception type exception based on the specified exception information, expected parameter type, and actual parameter type.
8. [S]Error. argumentundefined: Create a sys. argumentundefinedexception type exception based on the specified exception information and the defined parameter.
10. [S]Error. Create: Creates an error object based on the specified exception information.
12. [S]Error. invalidoperation: Create a sys. invalidoperationexception type exception based on the specified exception information and the parameter that causes the exception.
14. [S]Error. notimplemented: Create a sys. notimplementedexception type exception based on the specified exception information.
16. [S]Error. argumentoutofrange: Create a sys. argumentoutofrangeexception type exception based on the specified exception information and the parameter that causes the exception.
18. [S]Error. parametercount: Create a sys. parametercountexception type exception based on the specified exception information.
20. Error. popstackframe: Update the filename and linenumber fields of the error instance to the location when the error is thrown, rather than the location when the error is created.

 
// Throw a standard exception type
 

 
VaRErr = Error. argumentnull ("Input","A parameter was undefined .");
 

 
ThrowErr;
 

 
// Throw a generic error with a message and associated errorinfo object.
 

 
VaRErrorinfoobj = {Name:"Somenamespace. someexceptionname",
 

 
Someerrorid:"436"};
 

 
VaRErr = Error. Create ("A Test message", Errorinfoobj );
 

  throw  err;
