biginteger and bigfloat support missing values (via NA_biginteger_
and
NA_bigfloat_
respectively).
bigfloat additionally supports positive and negative infinity and 'Not a Number' values. Usually these are the result of a calculation, but they can also be created manually by casting from numeric to bigfloat.
These functions check for the presence of these special values. The base R
documentation can be found at is.na()
and is.finite()
.
