Can use convertUnit to round to 0 decimal places.     geolib.convertUnit('mi', 5000*1000, 0) === 3107 and     geolib.convertUnit('mi', 5000*1000) === 3106.856 while before,     geolib.convertUnit('mi', 5000*1000, 0) === 3106.856
Can use convertUnit to round to 0 decimal places.
    geolib.convertUnit('mi', 5000*1000, 0) === 3107
and
    geolib.convertUnit('mi', 5000*1000) === 3106.856
while before,
    geolib.convertUnit('mi', 5000*1000, 0) === 3106.856

Generally suggest using 
    arg = (null == arg ? DEFAULT : arg)
instead of
    arg = arg || DEFAULT
for giving default arguments.
