BigInteger.Log10(BigInteger) Method

Definition

Namespace:

System.Numerics

Assembly:

System.Runtime.Numerics.dll

Source:

BigInteger.cs

Returns the base 10 logarithm of a specified number.

public:
 static double Log10(System::Numerics::BigInteger value);

public static double Log10 (System.Numerics.BigInteger value);

static member Log10 : System.Numerics.BigInteger -> double

Public Shared Function Log10 (value As BigInteger) As Double

Parameters

value

BigInteger

A number whose logarithm is to be found.

Returns

Double

The base 10 logarithm of value, as shown in the table in the Remarks section.

Exceptions

ArgumentOutOfRangeException

The base 10 log of value is out of range of the Double data type.

Remarks

The value parameter is specified as a base 10 number.

The precise return value of the method depends on the sign of value, as the following table shows.

Sign of value parameter	Return value
Positive	The base 10 log of value; that is, log10value.
Zero	Double.NegativeInfinity.
Negative	Double.NaN.

To calculate the natural logarithm of a BigInteger value, call the BigInteger.Log(BigInteger) method. To calculate the logarithm of a number in another base, call the BigInteger.Log(BigInteger, Double) method.

This method corresponds to the Math.Log10 method for the primitive numeric types.
