int x =(int)23.45f; //valid 23 will be assigned to x;

byte b = 260; //error 260 is integer

byte b =(byte)260; //260%256 (range of byte data type)

=4 is assigned to b;

float f = 14.4878129878 //error

float f =(float)14.4878129878; or float f= 14.4878129878f;

NOTE: Loss of precession will occur as f will contain 14.487813, as fl oat allows only six digits of precision

whereas double allows 14 digits of precision.

In addition, all expressions involving either byte or short or both are internally converted to integer

before the operation is performed. For example: ...
