### Rounding in Random Numbers

I think I posted this in the wrong place yesterday, so I thought I would try it over here.   I am authoring a question that includes a random one digit decimal between -10 and 10, hence:

$a = random(-10,10,.1); I just happened to have seed 1612, and when printing out$a in the problem, instead of printing -0.02 (as I suspect it wanted to), it is printing out -0.1999999999.

I'm having the same issue with

random(-5,5,.1); with seed 4252

printing out -0.899999999999.

Any ideas on what I should do here?  Is there a way to restrict how many decimal places WeBWork displays?  Is this a known issue?  I tried searching the forums to not much avail.

I've gotten around this by replacing it with
