What is the source of BUG/Warning

[Pranav]

template <class X>
class Node{
:
:
};
template <class X>
class Link {
:
:
Node<X*a1, *a2;
};
int main( )
{
Link<floatlist1;
int ret=0, x;

list1.addnode(0.1234);
:
:
:
}

I am gettin followin Bug/Warning when I use <float>
warning C4305: 'argument' : truncation from 'const double' to 'float'
also my data gets truncated into float to int..,
But when I use double I get no bug/warning..,

What may be the possible source of the bug/warning?

The literal 0.1234 has the type 'double'. Your list 'list1' expects the
value of type 'float' (most likely, you didn't actually show), so the
compiler needs to truncate the value to fit (apparently 'double' and
'float' on your machine have different representations). You can get
rid of the warning if you add the 'f' suffix to your literal:

list1.addnode(0.1234f);
