Using Maple 16

Search "Scale"

Examples

Scale10(.5, 1000); gives 5*10 ⁹⁹⁹ (1)

Scale2(.5, 1000); gives 5.357543035 * 10 ³⁰⁰(4)

Appears to answer the question but dosen't.

The question is simple how to calculate 10^-6 x 10 ⁺¹⁵using scientific notation in Maple?

is there a scientific notation threshold

In an attempt to clarify... If I have not changed any of the options on a vanilla install, are there options somewhere that govern when a numeric answer will be converted to scientific notation? for example if I take 1/10 , 1/100, 1/1000, 1/10000 at what point will the answer be displayed as 1x10^x ? lets assume that it diplays .1, .01 ,.001, 1x10^-4 now I know that 10^-4 is the threshold. Is this threshold an option? Can it be changed in preferences? What if I want all my numeric answers in Scientific notation? Is this something that I can change? I assume it is in the precision tab under preferences but the choices there seem very nondescript and I can't find much in the help files on these options. Thanks, dgiznya

It doesn't change the display

Scale2 and Scale10 multiply the numbers by the appropriate power of 2 or 10, but they don't affect how the number is displayed. In the cases that you show, the number is displayed in scientifc notation because it is large. If you had used some smaller exponents, scientific notation wouldn't have been used.
