/**
 * Returns a random number in a given range. If the range is zero, a random
 * float between [0,1) is returned. If the range is a positive number, a
 * random integer between 1 and that number is returned (inclusive is returned).
 *
 * **NOTE:** the float returned is in the range [0,1) to match the javascript
 *     implementation, while the brightscript specification calls for (0,1).
 *     This should be okay in practice, but if this is necessary a more complicated
 *     implementation will be necessary.
