I was having a few problems calculating the difference of time a few days ago
and I posted some questions and I received a lot of great help. Although,
I'm still having problems. I'm not sure if I reply to a message in that old
post, if anyone will see it. Not sure how that works. Therefore, I'm
posting a new message.
This is what I have:

I don't understand why I'm getting different results when I do a paste
special. When I paste the time formula into certain cells, the result is
fine.
Then when I paste the formula into another cell, I'm getting a result of
16.9999999999999 and Excel will not allow me to decrease the decimals places.
Why is this happening and how can I get a result of 17 min.?

Cell F18 = 10:17 AM
Cell D18 = 10:00 AM
Cell H18 = The formula is: =(((F18-D18)*60)*24)&" min."
Result in H18 = 16.9999999999999

HELP!

Excel along with most PC programmes s not acurate to hundreds of decimal
places.
Floating point is notorously flacky.

You aren't subtracting 0 from 17, but 0.416666667 from 0.428472222
A result of 0.011805556, ie 17 minutes.
Though in my case this comes out as 17

In fact unless you have specified 13 decimal places I can't see how you
get your result

decide how accurate an answer you want.
If you want an answer to the nearest minute then just use the Round()
function

you are converting the number into text and running into a floating decimal
calculation issue if you want minutes only try
=round(((F18-D18)*60)*24,0)&" min."
you probably have something in I17 which keeps you from seeing the rest of
the text whihc would have the "min" portion
