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.
