CTS130 Spreadsheet Lesson 8 Rounding and Nesting Functions

INT Function (cont’d)  INT stands for “integer.” An integer is a whole number - a number with no decimal or fractional parts.  The INT function shows the nondecimal portion of a number.  Excel stores the full number of decimals that are keyed/calculated in a cell, even if cell is formatted to show fewer decimal places. Example: If you key in but format the cell for two decimal places, Excel displays 1.23 in the cell. In a calculation, Excel uses the full value, , when you see it in the formula bar.  The INT function has one argument, the value or cell to be adjusted.

The ROUND Function  The Round function “rounds” a value to a specified digit to the left or right of the decimal point.  “Rounding” means that it is made larger or smaller, a greater or lesser value.  The Round function uses two arguments: the value to be rounded and the number of digits used for rounding.

The ROUND Function (cont’d)  If a value referenced in a formula is rounded, the rounded value is used in the calculation.  If a value is formatted in a way that it appears rounded, the precise value is used in the calculation.

Using Date and Time Arithmetic to Determine Ages To determine a person’s age, subtract the person’s birthday from today. The result is a serial number that can be converted to the person’s age. =today( ) Dividing by includes a leap year once every four years.

Using Time and Date Arithmetic to Determine Time Worked Subtract the beginning time from the ending time. Excel shows time as a fraction of a 24-hour day. To convert to hours, multiply the results by 24. =(C4-B4)*24 # of hours in a day

How to Group Worksheets  When you want what you are doing on one worksheet to appear on all the worksheets, you can first group the worksheets.  To group worksheets, hold down the [CTRL] key and click each worksheet’s tab. All the worksheets will be selected.  To ungroup worksheets, click a single worksheet tab or right- click a worksheet tab and select the “Ungroup Sheets” option. Grouped WorksheetsUngrouped Worksheets

How to Hide and Unhide a Worksheet  You can hide a worksheet so that you do not see its tab while the workbook is open.  This allows you to hide sheets that include sensitive information that should not be easily visible. Format Menu > Sheet > Hide Format Menu > Sheet > Unhide A dialog box will appear displaying all the worksheets that are hidden.

Nested Functions A nested function is a function inside another function. This is an example of a nested round and sum functions. Function Name box Formula bar =ROUND(SUM)(H4:H8)

Nested Functions (cont’d) =IF(B9>400,”Over 400”,IF(B9>375, “Over 375”, Under Quota)) If TRUEIf FALSEIf TRUEIf FALSE NESTED

Nested Function Examples

Creating a Hyperlink  A hyperlink is a clickable object or text that, when clicked, displays another file, opens another program, shows a web page, or displays an address.  As you insert hyperlinks, Excel keeps a list of the addresses and shows them in the “Insert Hyperlink” dialog box.  You can key a new entry or choose existing name from the list.  Ways to insert a hyperlink: - Click the “Insert Hyperlink” button. - INSERT Menu > Hyperlink - CTRL + K - Right-click > Hyperlink

Saving a Workbook in Different Format If you send a workbook to someone who uses a different version of Excel or a different electronic spreadsheet program, you can save the file in an appropriate format for them. Two popular formats are:  WK4 (Lotus)  CSV (comma-separated values.
