Functions for BIGNUM representation of arbitrarily precise integers

Description

as.BIGNUMint encodes integer in BIGNUM format as raw vector as used by ASN.1 format.

Usage

as.BIGNUMint(what, scalar = TRUE)

Arguments

Details

The BIGNUM representation as used in ASN.1 is a big-endian encoding of variable length stored in a raw vector. Negative numbers are stored in two-complement's encoding, but are currently unsupported by as.BIGNUMint.

Value

Raw vector in BIGNUM integer representation.

Note

Unless the input is of class "bigz" then 32-bit platforms only support integers up to 32-bit, 64-bit platforms up to 53-bit (when real vectors are used).
