C# Класс Redzen.Structures.Compact.FixedPointDecimal

A fixed point decimal data type that has the following qualities: 1) Uses a Int32 to hold the value (4 bytes versus the native decimal's 16 bytes). 2) Defines a fixed number of six digits after the decimal place. 3) Allows a null value to be represented, requiring a single bit to allocated for this. The range of FixedPointDecimal is -1,073.741823 to 1,073.741823. This can therefore represent all possible values in the SQL data type decimal(9,6). The range takes into into account the null bit and the fixed four digits after the decimal place. Fixed point maths also has the benefit of allowing for far simpler/faster comparison.

Открытые методы

Метод	Описание
Compare ( FixedPointDecimal d1, FixedPointDecimal d2 ) : int	Compares two specified FixedPointDecimal values.
Create ( decimal d ) : FixedPointDecimal	Static factory method to create a FixedDecimal.
Equals ( FixedPointDecimal d1, FixedPointDecimal d2 ) : bool	Determines whether the specified FixedPointDecimal is equal to the current FixedPointDecimal.
Equals ( object value ) : bool	Determines whether the specified Object is equal to the current Object.
FixedPointDecimal ( decimal val ) : System	Construct FixedPointDecimal from the provided nullable decimal.
GetHashCode ( ) : int	Gets the hash code for the object.
TryParse ( string s, FixedPointDecimal &result ) : bool	Converts the string representation of a number to its FixedPointDecimal equivalent. A return value indicates whether the conversion succeeded or failed.
TryParseTruncate ( string s, FixedPointDecimal &result ) : bool	Converts the string representation of a number to its FixedPointDecimal equivalent. A return value indicates whether the conversion succeeded or failed. Values outside the range of a FixedPointDecimal are truncated to the min or max values for FixedPointDecimal as appropriate. Input values with more than four decimal places have their precision truncated to to four decimal places.
operator ( ) : bool	Determines if two FixedPointDecimal objects are not equal.

d1	FixedPointDecimal	The first to compare.
d2	FixedPointDecimal	The second to compare.
Результат	int

Create() публичный статический Метод

Static factory method to create a FixedDecimal.

public static Create ( decimal d ) : FixedPointDecimal
d	decimal	The value to create the object from.
Результат	FixedPointDecimal
