AI Thread Summary
To obtain approximate answers while the Exact/Approx setting is on "AUTO," users can press the Diamond button before hitting ENTER to solve. Another method is to include a decimal in one of the numbers during input, such as entering 4. / 3 instead of 4 / 3. If an exact answer is given and a decimal is desired, multiplying by 1 can convert it to a decimal format. These techniques provide effective alternatives for obtaining approximate results without changing the mode settings.

With the Exact/Approx set to "AUTO" in the mode menu, how can I get approximate answers without going and switching it to approx then recalculating?

Before you press ENTER to solve, press the Diamond button.
 
Woot! Thanks!

Put a decimal in one of the numbers, i.e., instead of entering 4 / 3, enter 4. / 3. If you forget, or if you an exact number answer that you want converted to a decimal, just x (times) 1.

Try both to see how they work!

Cool. Thanks for the alternatives.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
