[sonir shah]

Is long narrower than float and double??

byte = 8 bits

short = 16 bits

int = 32 bits

long = 64 bits

float = 32 bits

double = 64 bits

Yes!!!
Though it may sound a bit strange, a long can be implicitly converted to float or doube. Of course, there's a loss of precision in it, but JLS says it is valid.

i think they belong to different standards.

The logic behind the long->float promotion is that within a float, you can represent the order of magnitude of *every* possible long, although at the cost of some precision if you have a very big long.
i.e, Long.MAX_VALUE = 9223372036854775807
(float) Long.MAX_VALUE = 9.223372e18
