In case of casting a float / double value to int, you generally loose the fractional part due to integer truncation. This is quite different from rounding as we would usually expect, so for instance 2.8 ends up as 2 with integer truncation, just as 2.1 would end up as 2. Another source of potential (gross) inaccuracy with casting is ... bitcoin bank inscription https://cxautocores.com
