Imports of package rand

PathSynopsis
bufioPackage bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O.
crypto/aesPackage aes implements AES encryption (formerly Rijndael), as defined in U.S. Federal Information Processing Standards Publication 197.
crypto/cipherPackage cipher implements standard block cipher modes that can be wrapped around low-level block cipher implementations.
encoding/binaryPackage binary implements simple translation between numbers and byte sequences and encoding and decoding of varints.
errorsPackage errors implements functions to manipulate errors.
internal/syscall/unix
ioPackage io provides basic interfaces to I/O primitives.
io/fsPackage fs defines basic interfaces to a file system.
math/bigPackage big implements arbitrary-precision arithmetic (big numbers).
osPackage os provides a platform-independent interface to operating system functionality.
runtimePackage runtime contains operations that interact with Go's runtime system, such as functions to control goroutines.
syncPackage sync provides basic synchronization primitives such as mutual exclusion locks.
sync/atomicPackage atomic provides low-level atomic memory primitives useful for implementing synchronization algorithms.
syscallPackage syscall contains an interface to the low-level operating system primitives.
timePackage time provides functionality for measuring and displaying time.
