LB (Number)


  • is any positive real number.

Description

  • This function shows the logarithm value of base 2.
  • In  ,  is any positive real number.
  • LB means the logarithm with the base 2.
  • So the Binary logarithm is the logarithm to the base 2.
  • The Binary logarithm function is the inverse function of the power of two function.
  • So for any real number x,   , .
  • For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1, the binary logarithm of 4 is 2, and the binary logarithm of 32 is 5.
  • This function will return the result as NaN when the given number as negative.

Examples

  1. LB(20) = 4.321928094887363
  2. LB(192) = 7.584962500721156
