Bug in the below code

Calculates percentage downtime for a week in minutes.

/**
* calculates percentage down time
* @param downMins
* @return
*/
private double getUpPercentage(long downMins) {
double upPercentage = HUNDERED;
if (downMins > ZERO) {
upPercentage = (HUNDERED - ((downMins * HUNDERED) / TOTAL_WEEK_MINS));
}
return upPercentage;
}
