C# 0 The Complete Reference

false

 for a positive number 

and

true

 for a negative number. The scaling factor is passed in 

scaleFactor,

 which must be a 

value between 0 and 28. This factor specifies the power of 10 (that is, 10

scaleFactor

) by which the 

number is divided, thus yielding its fractional component.

Instead of passing each component separately, you can specify the constituents of a 

Decimal

 in an array of integers, using this constructor:

public Decimal(int[ ] 

parts

)

The first three 

int

s in 

parts

 contain the 96-bit integer value. In 

parts

[3], bit 31 specifies the 

sign flag (0 for positive, 1 for negative), and bits 16 through 23 contain the scale factor.

Decimal

 implements the following interfaces: 

IComparable

,

IComparable

,

IConvertible

,

IFormattable

, and 

IEquatable

.

Here is an example that constructs a 

decimal

 value by hand:

// Manually create a decimal number.
