Generate Random Sequence (rand)

Random field generator

Description

rand can generate random numbers, strings and other data types.

Usage

rand data-type [ max-value ]

Examples

Specifying data-type

Random integer (64-bit on 64-bit machines):

rand int

Specifying custom range

Random integer between 0 and 9:

rand int 9

Random floating point number between 0 and 1:

rand float

Random string, fixed to 5 characters long:

rand str 5

Flags

• * Alias for str (string)
• float Random floating point number between 0 and 1. max-value not supported
• int Random integer, max-value specifies highest value for integer
• num Alias for int in this builtin
• str Random string of printable ASCII characters. max-value specifies the fixed length of the string

Detail

Security

WARNING: is should be noted that while rand can produce random numbers and strings which might be useful for password generation, neither the RNG nor the the random string generator (which is ostensibly the same RNG but applied to an array of bytes within the range of printable ASCII characters) are considered cryptographically secure.
