As in the creation of vli objects (through the function as.vli), punctuation signs will be ignored (see the last example).
The algorithm implemented for the operator "*" computes the product with a trivial method when imput numbers have less than 40 digits and with the Karatsuba algorithm for fast multiplications when they are larger.
x <- as.vli("712376544526091241")
x ^ 61
x / as.vli("4225234")
x > -x
x <= 10000000
13.2415 - as.vli(132415)
