bignum-special {bignum}

Check for special values

Description

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().

Value

A logical vector.
