What is the rnd() method in Euphoria?

Overview

The rnd() method is an inbuilt method in Euphoria that generates a random number between 0 and 1. This method randomly generates floating-point numbers between 0.0 and 1.0 (both inclusive).

This is unlike the rand() method, which only returns integer numbers.

Syntax

rnd()

Parameter

This method has no parameters.

Return value

This method returns a random value between 0.0 and 1.0, with both ends inclusive.

Code

The code below shows how the rnd() method generates a random floating-point number.

include std/rand.e
--declare the variable to hold the output
atom output
--use a for loop to print different floating numbers
for i = 1 to 6 do
    puts(1,"\n")
    output = rnd()
    print(1,output)
end for

Explanation

  • Line 1: We include the rand.e module from the built-in library.
  • Line 4: We declare the output variable.
  • Lines 7 and 11: We start and end a for loop.
  • Lines 9 and 10: We use the rnd() method and print the outcome to the screen.
