0.999… = 1
The endless nines are exactly one, not ‘almost one’
0.999…, with nines that never end, feels like it stops just short of 1. So how much is missing, exactly?
You'll find out
- What number fits between 0.999… and 1
- What one third has to say about it
- What the three dots really promise
Why it matters
Calculus, the math behind physics and engineering, starts here: an endless sum can have an exact total.
