biginteger and bigfloat vectors support many of the standard mathematical
operations. The base R documentation can be found by searching for the
individual functions (e.g. mean()).
The returned value depends on the individual function. We recommend reading the base R documentation for a specific function to understand the expected result.
Other bignum operations:
bignum-arith,
bignum-compare,
bignum-special
