biginteger() and as_biginteger() construct a vector designed to store
any integer.
is_biginteger() checks if an object is of class bignum_biginteger.
biginteger(x = character())
as_biginteger(x)
is_biginteger(x)Object to be coerced or tested.
An S3 vector of class bignum_biginteger.
NA_biginteger_ to represent missing values.
format() for pretty printing.
vignette("operations") for supported operations.
