NumberParser code (.NET/C#) >
NumberX is the generic designation for the following four basic classes of NumberParser:
  • Number. The most simple and efficient one. It is decimal-based.
  • NumberD. Similar to Number, but capable to deal with any numeric type via dynamic.
  • NumberO. It manages different numeric types simultaneously. The code of its specific functionalities is being analysed in the next section.
  • NumberP. It parses strings into numeric types. There is one section analysing its specific code.
All NumberX have the following public fields in common:
  • Value. Main numeric information of the given variable. Its type can be either decimal or dynamic (i.e., any supported numeric type).
  • BaseTenExponent. Exponent of the base-ten factor which complements Value when required (i.e., being outside the range of the corresponding numeric type). For example, Value 6 and BaseTenExponent 3 equals 6*10^3 or 6000.
  • Error. An ErrorTypesNumber variable telling the user about any error, which is managed internally without raising exceptions.
All NumberX have also the following features in common:
  • Custom overloaded functionalities.
    • Arithmetic operators. Number number = new Number(1m) + 2m;
    • Comparison operators. if (new NumberO(1m) < 2m) { //This condition is true. }
    • Implicit conversions between each other. Number number = new NumberD(1);
    • Implicit conversions of related types. NumberP numberP = "1.2";
  • Custom arithmetic operations accounting for their basic Value-BaseTenExponent-Error structure and managing all the errors internally (i.e., never raising exceptions).
    Most of this code is included in Operations_Private_Managed.cs. The contents of this file are very similar to the ones of UnitParser's Operations_Private_Managed.cs and, consequently, the explanations in the corresponding UnitParser section are somehow applicable here too.
