# Generating integers between in a range, excluding zero browsing

• There are a couple of ways to achieve this depending of what you are trying to do.

Using Maple T.A. only functions you can use three random numbers and a switch statement to achieve this.

# random integer from -5 to 5 excluding 0

$a=switch(rint(2),rint(5)-5,rint(5)+1);  An alternative using a Maple call and only one random number and an if statement is # Create a procedure called gen(). If you want a number random number you just call gen() again. # Below we can see the variables a and b are both random numbers.$alg=maple("
randomize():

gen := proc ()
local roll, r;
roll := -5+rand(10);
r := roll();
if 0 <= r then
r := r+1
end if;
r
end proc:

a:=gen():
b:=gen():
")


There is a cost to the maple call and a cost to rolling three random numbers. Experiment with your algorithm to find out which is best.
