LOGSTAR (Number,Base)


  • is any real number.
  • base value of the log.

Description

  • This function shows the iterated logarithm of the given number.
  • In , is any real number.
  • is the base value of the log.
  • Log star is the number of times the logarithm function must be iteratively applied before the result is less than or equal to 1.
  • The simple definition of the Log star is :

<math>\begin{cases} 0 & if n\le 1 \\ 1+log*(log n) & ifn > 1 \\ \end{cases}

  • The relation between Log star and Super logarithm is log*n=[slog_e(n)] for positive real numbers.
  • Also for negative real numbers ,log star value is 0,whereas
