Raj: I agree, in this scenario it makes no difference, however when we are
applying a fomular the unit conversion should happen prior to applying
values.
Still I see a problem with this correction, take the same example:
Gradient: -999.9999999999998 Last val: 7.000000000000001 First val: 12.0
Time Gap: 5 t1: 1415213232152 t2: 1415213232157
*Manual calulation:*
The value difference: 7 - 12 = -5
Time difference: 1415213232157 - 1415213232152 = 5 ms => 5/1000 = 0.005 sec
*Gradient = - 5/0.005 = -1000*
*According to the current fix:*
long millisecondsForASecond = 1000;
long tGap = t2 - t1 > millisecondsForASecond ? t2 - t1 :
millisecondsForASecond;
double gradient = 0.0;
if (tGap > 0) {
gradient = ((lastVal - firstVal) * millisecondsForASecond) /
tGap;
}
t1: 1415213232152 t2: 1415213232157 firstVal: 12 lastVall: 7
Gradient = -5 * 1000 / 1000 = - 5
Nirmal: Can you please justify this?
Thanks
