DivRem(Int64, Int64, Int64)

Calculates the quotient of two 64-bit signed integers and also returns the remainder in an output parameter.

public:
 static long DivRem(long a, long b, [Runtime::InteropServices::Out] long % result);

public static long DivRem(long a, long b, out long result);

static member DivRem : int64 * int64 * int64 -> int64

Public Shared Function DivRem (a As Long, b As Long, ByRef result As Long) As Long

Parameters

a: Int64

The dividend.

b: Int64
