Splitting a number into integer and decimal portions

Here is a quick formula tip to start another awesome week.

Often while working with data, I need to split a number in to integer and decimal portions. Now, there are probably a ton of ways you can do this. But here are two formulas I use quite often and they work well.

Assuming the number is in cell A1,

• Integer part =INT(A1)
• Decimal part =MOD(A1,1)

These formulas work whenever my data has only positive numbers (which is the case 90% 0f time). But if I am dealing with a mix of positive and negative numbers, I use,

• Integer part =INT(A1) +(A1<0)=TRUNC(A1,0) [thanks to Somnath for suggesting this]
  
• Decimal part =MOD(A1,SIGN(A1))

What formulas do you use to process numbers?

I use a lot of formulas while working with numbers. But my favorite ones are MOD, INT, SIGN, ABS, RAND and RANDBETWEEN (new in Excel 2007, requires Analysis toolpak in earlier versions).

What about you? What formulas do you use and how do you process your numbers? Please share using comments.
