On page 12 it states that 2546789.343 is a double. Also on question 9, p 48, the answer states that B 3.14 is a float as well. How can you tell it is a double and not a float? I guess my question is how can you tell if a number is a float or a double by just looking at it. Thanks. ed
If the number has a decimal point (3.14) or uses scientific notation (5e6) then it is a floating point number. If it has an f or F at the end (3.14f) then it is a float. otherwise it is a double. 3.14 is a double, not a float.
hi ed suttner How can you tell it is a double and not a float? If you have time, I prefer to use the method that using the compiler to test the programme. Because we may be confused by the content of book which may be wrong.
No. No. No. No. Changed my mind. Wanna come down. To see this tiny ad:
