1.5 vs 1.5f

[lochnessmonster]

im curious is there a difference between
const float f = 1.5F;
vs.
const float f = 1.5;

is there a difference??

1.5 is a double, 1.5F is a float

Well, in this case, there is no difference. By default, floating point literals are double precision.

So, 1.5 is double by default.

Check this out:
http://babbage.cs.qc.edu/IEEE-754/Decimal.html

Thus,

1.1 != 1.1f

So,

const double  f1 = 1.1F;
const double  f2 = 1.1;

Here, f1 != f2 (which can be seen why from the link)

Oops, didn't see your post.

>is there a difference??
The latter will probably give you a warning about loss of precision, but since the value is representable by both float and double, there's no real problem.
