LOGSTAR (Number,Base)
- is any real number.
- base value of the log.
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
