Extracting Integers and Fractions in Microsoft Excel

Sometimes you need to extract the integer portion of a number. Sometimes the fractional part. Sometimes both. Excel makes it easy to get the integer and somewhat harder to get the fraction. If you just want the answer, skip to the technical details.

The Integer Part: Excel INT Function

What could be easier than the Excel INT function? I mean INT almost screams INTEGER. So the name is intuitive. You almost “know” what it’s going to do, even if you haven’t used it before.

With only one argument, it’s execution is even simpler. Just … Read the rest

MOD Function Time Extract

Extract Time with the MOD Function in Excel

I had a reader comment on my last post about how to extract time from a date-time number using the MOD function. Simple really.

The syntax is MOD(number,divisor). The MOD function returns the remainder after number is divided by divisor. A simple example is MOD(5,2), which equals one (1). It works like this: five (5) divided by two (2) equals two (2), with one (1) left over.

All numbers are evenly divisible by one (1) so the MOD function returns any fractional part when the second argument is one (1).

Horizontal Dynamic Dependent Drop Down List Example

A Dynamic Dependent Drop Down List with a Horizontal Table Reference

I received a comment asking if a dynamic dependent drop-down list in Excel could have a list where the “table headers were actually rows and not columns?” Since I’ve already detailed how this is done in the article mentioned above, I’ll keep this short.

The VLOOKUP Function – Inside Out

vlookup sharkAs part of Shark Week I’ve committed to write something for VLOOKUP week. (It’s what I get for using twitter.) So without further ado.

I love the VLOOKUP Function in Excel. As the name implies, it’s a vertical lookup. Meaning the function will lookup data in columns.

The VLOOKUP Function Arguments

The VLOOKUP function has four arguments and in my opinion the fourth argument always gets overlooked, yet it’s the first thing you need to know. So, like reverse polish notation, we’ll start from the inside and work out to explain each argument.… Read the rest

How to Update a List or Range without OFFSET

I avoid the use of Volatile Functions, especially OFFSET, which is commonly used to update a list or range. They can slow down the operation of your workbook. For very large workbooks with lots of data, it can be significant and irksome.

Worksheet cells that use Data Validation for a drop-down list can simplify the input process, or be used to limit the available choices. But the list needs be expandable. Here are two primary ways to keep your data validation list automatically updated, without having to resort to using the OFFSET function.

Fill Down a Formula with VBA

I commented on a post that brought to light, the fact that, using the cell fill-handle to “shoot” a formula down a column doesn’t always work when the adjacent column(s) have blank cells. So I decided to share some Excel VBA code that’s used to copy a formula down to the bottom of a column of data.

The situation is depicted below. Cell C2 is active, and has the formula =B2+A2. I want to copy it down to the rest of the column in this data range. However, cells B6 and B11 are empty, along … Read the rest
