Hello Everyone -

When use a series of data and create a chart - then from that create a
treadline to forecast future values - sometimes the formula Excel provides
(used to forecast the future values) is, im guessing, to big or too long and
Excel will place an E next to a number.

Here is an example: y = 762870x + 5E+06


How can I see the equation in its entirety so I can use it?


Thanks!
 
MC -

Several possibilites:

(1) Select the equation, and then Format it. Method depends on Excel
version, which you didn't specify.

(2) For a linear trendline, use the INTERCEPT and SLOPE worksheet functions
(or array-entered LINEST, especially if you want diagnostics).

(3) Or, for linear forecasts, use the array-entered TREND worksheet
function.

Haha yes I did mean trendline thanks for that correction. I do not know what
I was thinking when I wrote that.

I do not know how to use the LINEST, TREND, or LOGEST functions, but I was
using the trendline to forecast future expenses, assuming they increase in a
linear fashion (which is more than likely not the case, but it works well
enough).

Thanks for the help - It is much appreciated David and Mike!
