Integer N-th Root
Determine the integer n-th root of .
iNthroot(p, n)
p |
any positive number. |
n |
a natural number. |
Calculates the highest natural number below the n-th root of
p in a more integer based way than simply floor(p^{1/n}).
An integer.
iNthroot(0.5, 6) # 0
iNthroot(1, 6) # 1
iNthroot(5^6, 6) # 5
iNthroot(5^6-1, 6) # 4
## Not run:
# Define a function that tests whether
isNthpower <- function(p, n) {
q <- iNthroot(p, n)
if (q^n == p) { return(TRUE)
} else { return(FALSE) }
}
