What's the difference between a single precision and double precision floating point operation?
...its long.
The extra bits increase not only the precision but also the range of magnitudes that can be represented.
The exact amount by which the precision and range of magnitudes are increased depends on what format the program is using to represent floating-point values.
Most computers use...

Take the content of a list and append it to another list
...instead of
list2.append(list1)
Here's the difference:

What is the difference between declarative and imperative programming? [closed]
...want.
A simple example in Python:
# Declarative
small_nums = [x for x in range(20) if x < 5]
# Imperative
small_nums = []
for i in range(20):
if i < 5:
small_nums.append(i)
The first example is declarative because we do not specify any "implementation details" of building the ...
