Coerce to integer64

Methods to coerce from other atomic types to integer64.

Usage

as.integer64(x, ...)

# S3 method for class '`NULL`'
as.integer64(x, ...)

# S3 method for class 'integer64'
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 'character'
as.integer64(x, ...)

# S3 method for class 'factor'
as.integer64(x, ...)

# S3 method for class 'bitstring'
as.integer64(x, ...)

NA_integer64_

Format

An object of class integer64 of length 1.

Arguments

x

an atomic vector

...

further arguments to the NextMethod()

keep.names

FALSE, set to TRUE to keep a names vector

Value

The other methods return atomic vectors of the expected types

Details

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' and ' ' 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.
