# BigInteger.GreaterThanOrEqual Operator (Int64, BigInteger)

.NET Framework 4.5

Returns a value that indicates whether a 64-bit signed integer is greater than or equal to a BigInteger value.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)
```public static bool operator >=(
long left,
BigInteger right
)
```

#### Parameters

left
Type: System.Int64

The first value to compare.

right
Type: System.Numerics.BigInteger

The second value to compare.

#### Return Value

Type: System.Boolean
true if left is greater than right; otherwise, false.

The GreaterThanOrEqual method defines the operation of the greater than or equal to operator for BigInteger values. It enables code such as the following:

```BigInteger bigNumber = BigInteger.Pow(Int32.MaxValue, 4);
long number = Int64.MaxValue;
if (number >= bigNumber) {
// Do something;
}
```

Languages that do not support custom operators can call the BigInteger.CompareTo(Int64) method instead. Some languages can also call the GreaterThanOrEqual(Int64, BigInteger) method directly, as the following example shows.

```Dim bigNumber As BigInteger = BigInteger.Pow(Int32.MaxValue, 4)
Dim number As Long = Int64.MaxValue
If BigInteger.op_GreaterThanOrEqual(number,bigNumber) Then
' Do something
End If
```

If left is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the operation is performed.
