Why should I use a float?

Question

I mean what's the difference if I type print float(5+1) and print int(5+1) ??

Answer 1

The Python course goes over this.

float's are decimal numbers.
print(float(5+1))
Will print 6.0

int's are whole numbers.
print(int(5+1))
Will print 6

float(#something
)
Will convert (cast) the something to type float.

Answer 2

Well, a float is more useful when you have a different example like 1.5 +5.0 and that is 6.5 maybe you have been thinking on this.

But It depends if that result can be affected like for example if it is a banking account imagine that you have $6.00 obviously you care about the floats.
Another example could be a university grade you care if it is a 6.45 or a 7.00
