Are you trying to convert Integer wrapper to float or primitive type int to float?

Hi Ragi,

Can you please post your code here , that will make things clear. you can definitely assign an integer to float variable because its comes under float range .

Thanks

Top of my head:



int takes up less space in memory than float. I believe that Head First Java explained this beautifully when they mentioned cup size. int is a smaller cup than float, hence you can pour the contents of a small cup into a big cup without fear of it spilling over.

funny thing is, both int and long both fit into a float, despite long being a 64 bit integer. Ie: it can still be converted into a float without casting, even though a float is 32 bits.... go figure, but I believe the explanation is that "floats are weird" :P
