DivRem Example Syntax VB.NET ASP.NET | DivRem | Source Code
Summary: – Illustrates using DivRem with Source Code Syntax Example in VB.NET ASP.NET.
Purpose:
takes an dividend, divisor, and remainder as Int32 or Int64
and returns quotient as same data type. Remainder is passed by
reference and it gets updated with the remainder when the function
executes.
Syntax:
DivRem(dividend32, divisor32, byRef remainder32)
DivRem(dividend32, divisor32, byRef remainder32)
Parameters | Description | dividend32 | int32 |
---|---|
divisor32 | int32 |
remainder32 | byRef int32 |
Result Data Type | Description | int32 | quotient |
---|
Quick Example | Dim int32Dividend As Int32 = 7 Dim int32Divisor As Int32 = 5 Dim int32Quotient As Int32 = 0 Dim int32Remainder As Int32 = 0 |
---|
Syntax2:
DivRem(dividend64, divisor64, byRef remainder64)
DivRem(dividend64, divisor64, byRef remainder64)
Parameters | Description | dividend64 | int64 |
---|---|
divisor64 | int64 |
remainder64 | byRef int64 |
Result Data Type | Description | int64 | quotient |
