CUInt Example Syntax VB.NET ASP.NET | CUInt | Source Code
Summary: – Illustrates using CUInt with Source Code Syntax Example 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)
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 |
