Couldn’t find anything in the help files, and you guys have helped me before.

I want one cell in a Microsoft Excel spreadsheet to copy the value of another cell, but eliminating the decimals without rounding. If cell C12 contains 5, 5.25, 5.5 or 5.75, I want cell E16 to contain 5.

While ROUNDDOWN does a great job of letting you specify precision E.g.,
A2 = 7.356
B2 = 9.233
C2 = =ROUNDDOWN((A2B2),2) gives 67.91 while
=ROUNDDOWN((A2B2),3) gives 67.917
and
=ROUNDDOWN((A2*B2),0) gives 67
and so on,

if you already know that it is specifically an integer you want in the answer, INT() takes several fewer keystrokes.
