BigInteger.BitLength Method

  • Reference

Definition

Namespace:
Java.Math
Assembly:
Mono.Android.dll

Returns the number of bits in the minimal two's-complement representation of this BigInteger, <em>excluding</em> a sign bit.

[Android.Runtime.Register("bitLength", "()I", "GetBitLengthHandler")]
public virtual int BitLength ();
[<Android.Runtime.Register("bitLength", "()I", "GetBitLengthHandler")>]
abstract member BitLength : unit -> int
override this.BitLength : unit -> int

Returns

Int32

number of bits in the minimal two's-complement representation of this BigInteger, <em>excluding</em> a sign bit.

Attributes
RegisterAttribute

Remarks

Returns the number of bits in the minimal two's-complement representation of this BigInteger, <em>excluding</em> a sign bit. For positive BigIntegers, this is equivalent to the number of bits in the ordinary binary representation. For zero this method returns 0. (Computes (ceil(log2(this < 0 ? -this : this+1))).)
