Help me understand minute to decimal totals.​

Time Concepts

Notice that the correct exact decimal equivalent of 3 minutes is .05.  

 

   1 min  (.01666...)

+ 2 min  (.03333...)

   3 min  (.05000   )

 

Notice that manually adding the displayed total of the detail record is not as accurate...

 

.01

.03

.04

 

the NOVAtime software takes each record to the 4th decimal place (the ten thousandths place)...
