HOW TO extract decimal part or integer part from a Decimal number in C# or VB.NET

Exaples to extract decimal part or integer part from a Decimal number in C# or VB.NET

VB.NET
[sourcecode lang=”VBNET”]
Dim myDecimal As Decimal = 3.7 ‘myDecimal = 3.7
Dim integer_part As Integer

integer_part = Decimal.Truncate(myDecimal) ‘integer_part = 3

integer_part = Decimal.ToInt16(myDecimal) ‘integer_part = 3
integer_part = Decimal.ToInt32(myDecimal) ‘integer_part = 3
integer_part = Decimal.ToInt64(myDecimal) ‘integer_part = 3
integer_part = Decimal.Floor(myDecimal) ‘integer_part = 3

‘Following lines cause a Round (WRONG RESULT)
Dim rounded_integer_part As Integer
rounded_integer_part = myDecimal ’rounded_integer_part = 4, result different from C#
rounded_integer_part = Decimal.Ceiling(myDecimal) ’rounded_integer_part = 4

‘Obviously decimal_part is calculated as difference
Dim decimal_part As Decimal
decimal_part = myDecimal – Decimal.Truncate(integer_part) ‘decimal_part = 0.7
[/sourcecode]

C#
[sourcecode lang=”csharp”]
Decimal myDecimal = 3.7M; //myDecimal = 3.7
int integer_part;

integer_part = (int)Decimal.Truncate(myDecimal); //integer_part = 3

integer_part = (int)Decimal.ToInt16(myDecimal); //integer_part = 3
integer_part = (int)Decimal.ToInt32(myDecimal); //integer_part = 3
integer_part = (int)Decimal.ToInt64(myDecimal); //integer_part = 3
integer_part = (int)Decimal.Floor(myDecimal); //integer_part = 3
integer_part = (int)myDecimal; //integer_part = 3, result different from VB

//Following line cause a Round (WRONG RESULT)
int rounded_integer_part = (int)Decimal.Ceiling(myDecimal); //rounded_integer_part = 4

//Obviously decimal_part is calculated as difference
Decimal decimal_part;
decimal_part = myDecimal – Decimal.Truncate(integer_part); //decimal_part = 0.7

HOW TO make VB to C# or C# to VB conversion code

With this HOW TO I would like to put together tips to make the code conversion VB to C# or C# to VB.

VB C#
Asc Convert.ToInt32();
Chr Convert.ToChar();
Len String.Length();
Mid String.Substring();
ChrW(65) System.Convert.ToChar(65).ToString();
AscW('A')
System.Convert.ToInt32('A').ToString();

This post will be updated continuously by inserting each time new information.

Any suggestion is welcome.
