I've read about the difference between double precision and single precision Let's consider the following simple code snippet in java However, in most cases, float and double seem to be interchangeable, i.e
Using one or the other does not seem to affec. A simple comparison of two double values in java creates some problems From what i have read, a value of data type double has an approximate precision of 15 decimal places
Using long double i get 18/19 = 0.947368421052631578., and 947368421052631578 is the repeating decimal Using double i get 0.947368421052631526.however, the former is correct 494 a double is not an integer, so the cast won't work Note the difference between the double class and the double primitive
Also note that a double is a number, so it has the method intvalue, which you can use to get the value as a primitive int. Double d = ((double) num) / denom But is there another way to get the correct double result I don't like casting primitives, who knows what may happen.
I have a primitive float and i need as a primitive double Simply casting the float to double gives me weird extra precision
