How to round off ten random numbers in array?

Question

Trying to generate ten numbers which are random and without decimal point.

my @randoms = map { rand } (1..10)

This code returns ten random numbers yet with decimal like 0.218220758325518.

I want round off these numbers.

Need a help. Thanks.

rand can take a parameter that specifies the supremum of the generated numbers. Just call int to truncate it:

my @randoms = map int rand 20, 1 .. 10;

It generates numbers in the range 0 .. 19.
