CUInt Example Syntax VB.NET ASP.NET | CUInt | Source Code

Summary: – Illustrates using with in VB.NET ASP.NET.



Purpose:
Converts numbers into UInteger data type – UInteger data type is a
32-bit (4-byte) unsigned integer that can hold values from 0 to about 4
billion (4,294,967,295). Rounds fractions to whole numbers

Syntax:
CUInt(expression)

Parameters Description
expression 0 to 4,294,967,295 – will throw exception if negative number is passed in.
Rounds fractions to whole numbers

Result Data Type Description
UInteger 32-bit (4-byte) unsigned integer

Quick Example
Dim UInteger1 As UInteger = CUInt(1.33)
TextBox1.Text = UInteger1 Returns 1
