Coerce to integer64
Methods to coerce from other atomic types to integer64.
NA_integer64_ as.integer64(x, ...) ## S3 method for class 'integer64' as.integer64(x, ...) ## S3 method for class 'NULL' as.integer64(x, ...) ## S3 method for class 'character' as.integer64(x, ...) ## S3 method for class 'bitstring' as.integer64(x, ...) ## S3 method for class 'double' as.integer64(x, keep.names = FALSE, ...) ## S3 method for class 'integer' as.integer64(x, ...) ## S3 method for class 'logical' as.integer64(x, ...) ## S3 method for class 'factor' as.integer64(x, ...)

as.integer64.character is realized using C function strtoll which does not support scientific notation.
Instead of '1e6' use '1000000'.
as.integer64.bitstring evaluates characters '0' anbd ' ' as zero-bit,
all other one byte characters as one-bit,
multi-byte characters are not allowed,
strings shorter than 64 characters are treated as if they were left-padded with '0',
strings longer than 64 bytes are mapped to NA_INTEGER64 and a warning is emitted.
The other methods return atomic vectors of the expected types
