# Builtins.rand(3kaya)

Pseudo-random signed integer generator

## NAME

Builtins::rand - Pseudo-random signed integer generator

## SYNOPSIS

**Int rand(** **)**

## DESCRIPTION

**rand()**  returns a pseudo-random signed integer in the range +/- (2\*\*31)-1

You must call **Builtins.srand (3kaya)** before the first call to this function in a program.

-

   srand(12345);\
    for i in \[1..5\] {\
        putStr(rand()+" ");\
    }

Gives: *1995772607 -612336503 -885735441 457910745 1875493919*

The **rand()**  function is a low-quality but fast generator - for better quality numbers, use the optional **Lfrand(3kaya)** module or for cryptographic purposes, your computer's hardware RNG.
