TITLE: Is there another name for this "power of two" sequence?
QUESTION [5 upvotes]: I was recently asked how to call a number sequence, and since I am not sure about naming conventions, I am grateful for any help.
There is a sequence of real numbers, where:

the next element always equals the previous element, multiplied by 2
1 is included

A slice of this sequence will look like that: 0.0625, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32.
Is there a well-known name for this sequence? I see powers of two, starting from 1, but is there a name like “integers” or “Fibonacci numbers”?
Are there separate names for an integer part and fractional part?
I saw several names in OEIS, but what about fractional part?

REPLY [7 votes]: It is called a geometric progression of common ratio 2. The first element of the sequence is the scale factor.
