C-Sharp Truncate Example – Code Sample Syntax
C-Sharp Truncate Example – Code Sample Syntax
Purpose: – Illustrates using C-Sharp Truncate Code Example.
Purpose:
takes a decimal or double as input parameter1
and returns the number truncated without the
fractional decimals.
Syntax:
1. Truncate(decimal)
2. Truncate(double)
1. Truncate(decimal)
2. Truncate(double)
Parameters | Description | decimal | Any valid System.Decimal data type number double – any valid System.Double data type. Parameter1 specifies the number to be Truncated |
---|
Result Data Type | Description | decimal or double | depends on data type of parameter1. It is decimal, if parameter1 is decimal. If parameter1 is double, result is double. |
---|
Quick Example | Truncate(3.5) // Returns 3 |

Notes:
- Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
- You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.cs
