I just looked at this and the last excel example provided. You need to understand how to calculate Mean Time Between Failure and Mean Time To Repair before you apply it in to your excel data. MTBF is The Sum of (start of downtime - start uf uptime) all divided by no of failures. This will need to be by asset or system type and not all failures.
It means "raise to the power of" so that 2^3 means 2 raised to the power of 3 (or 2 cubed) which equals 8 ...
Re: What does -- mean in an excel formula? It coerces TRUE and FALSE to the numbers 1 and 0 respectively. Often used in an array formula, or a formula using a function like SUMPRODUCT which acts on an array, to convert a series of TRUEs and FALSEs to 1s and 0s which can then be added (or multiplied).
It means that the formula is calculated relative to the active sheet, rather than a named sheet. This can be useful. One way it is useful is by preventing you from having to enter the same formula multiple times for multiples sheets. For example, let's say you have the named range CircleArea with the formula: =PI()*Sheet1!A1^2
3) Algebraically rearrange the Arrhenius equation to get T at k, and use that formula in Excel to get the mean kinetic temperature. Register To Reply 08-02-2012, 11:00 AM #6
It would help if you posted the whole formula, but "," is usually hardcoding a comma somewhere. Anything that is between a set of quotes, is usually being treated as text.
OP's formula returns the value of A2. If A2 is "", then it returns "". However, if A2 is blank (in the ISBLANK sense), then the OP's formula returns 0 rather than "". This is one of several places where it's important to understand the difference between blank and "". > "calline6" wrote: >>then does it mean, for instance in the b.m. formula, >>
The brackets indicate an Array Formula. It changes how Excel handles the calculations. To enter an array formula, use the key combination CTRL-SHIFT-ENTER rather than just Enter.

Let's say you had the formula: =TRANSPOSE(F3:H3*F4:H4) in cell B3. Then =B3# would return the entire spilled range output to cell B3. In this case, B3:B5. So, if you use =B3# in another formula, you would generate a spilled range based on the original cells. Note that you can have spilled ranges in Structured Tables ... it's not happy.
