bignum-math {bignum}

Mathematical operations

Description

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()).

Value

The returned value depends on the individual function. We recommend reading the base R documentation for a specific function to understand the expected result.
