Function Names
randomDescription
Generates a random integer number. Biggest range (from lower to upper boundary) is 2^31-1.
Vectorization: This function supports vectorization. Sets and nested sets containing numeric values are also supported.
Call as: function
Restrictions
Indirect parameter passing is disabled
Vectorization is allowed in the 1st function parameter
Parameter count
1, 2
Parameters
| No. | Type | Description |
|---|---|---|
| 1. input |
numeral set |
1st boundary value If specified alone, then random numbers returned lie between 0 and specified value. Multiple values can be provided in a set for vectorization. |
| Opt. 2. input |
numeral set |
2nd boundary value If specified, then it will serve as 2nd boundary value. It does not matter if it is smaller or greater than the 1st boundary value. Multiple values can be provided in a set for vectorization. |
Return value
| Type | Description |
|---|---|
| numeral set |
Random number Randomly generated number(s) |
Exceptions
Values provided is not a numerals

for (i[]=1, i[]<=10, i[]++) print( random(1000), " " ); echo;
for (i[]=1, i[]<=10, i[]++) print( random( 1000, 950), " " ); echo;
for (i[]=1, i[]<=10, i[]++) print( random(-1000, -950), " " ); echo;
for (i[]=1, i[]<=10, i[]++) print( random( -5, 3), " " ); echo;
for (i[]=1, i[]<=10, i[]++) print( random( -1, 1), " " ); echo;
echo;
echo("Vectorization exmaple: ", random({10:1000}) ); // Provide 10 random numbers.Output
