BigInteger.GetBitLength 方法

定义

命名空间:
System.Numerics
程序集:
System.Runtime.Numerics.dll

获取当前实例的最短两个补码表示形式（不带符号位）所需的位数。Gets the number of bits required for shortest two's complement representation of the current instance without the sign bit.

public:
 long GetBitLength();
public long GetBitLength ();
member this.GetBitLength : unit -> int64
Public Function GetBitLength () As Long

返回

Int64

不带符号位的两个补码表示法中的最小非负位数。The minimum non-negative number of bits in two's complement notation without the sign bit.

注解

如果当前对象的值等于或，则此方法返回 0 Zero MinusOne 。This method returns 0 if the value of current object is equal to Zero or MinusOne. 对于正整数，返回值等于普通二进制表示形式的字符串长度。For positive integers the return value is equal to the ordinary binary representation string length.
