lol

in the context of computer science, 5.0 != 5
one if a floating point number, and caries the necessary information to distinguish it as such. the other is an integer and carries less information, and can be manipulated in simpler ways.

No. Everything in math is a set, and those two sets are not equal.

In number theory, my prof made a point about us not using equality between members of Z and Z/Z_p.

Even in non-comp-sci they are not always equal. In real world measurements, you don't have infinite precision. So you should give as much digits as your precision allows.
5.0 implies a precision of around ± 0.1, where as 5 implies a precision of around ± 1.
In the same way, if your precision only allows for differences of around ± 1, you should not write 5.0.

No.
5.0 can be any number from 4.95 to 5.04.
5 can be any number from 4.5 to 5.4

what?
that doesn't contradict 5 being equal to 5.0 at all.

>>8803601
5 implies ± 0.5
5.0 implies ± 0.05
So 5 can be between 4.5 and 5.4.
And 5.0 can be between 4.95 and 5.04.

>>8803607
>5 implies ± 0.5
no
>5.0 implies ± 0.05
no

>>8803609
With real-world measurements it does. See >>8803591

>With real-world measurements it does.
sorry then
>implying real-world measurements

>>8802749
Isn't one more precise? What's the context?

>>8803611
Yeah because real world instruments are only sensitive up to 1 decimal place.
