Question: Control the display of numbers?

I'm using Maple TA with first-year business students.

How do I control the display of numbers in Maple TA questions? If I define a variable to be 10000, it shows up as 100,000, which is easy to read. If I do some simple arithmetic, the result may show as 50000, which is easy for students to mistake as 500000 or 5000.
Another example is when I try rounding numbers. For instance, I want a random sample of size 8 from a normal distribution, and I'll have students do some calculations. I am going to call these numbers incomes, and I would like them to be rounded to the nearest 100. I've used the following algorithm, which works in Maple:
$a = maple("Statistics[Sample]('Normal'(30000, 10000), 8)");
$v1 = maple("evalf($a[1],3)");
...
However, in Maple TA, the result is written in scientific notation, like .315E05. I have business students and the notation is irrelevant and confusing. Can I control how numbers display, in ordinary "comma" notation?

Thanks in advance
