C# Class 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.

Public Methods

Method Description
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.
