>>> math.floor(4.4), math.floor(4.5), math.floor(5.4), math.floor(5.5)
(4.0, 4.0, 5.0, 5.0)

Logic to test that 3 of 4 are True
... ...
This is well defined in C++: the standard (§4.7/4) indicates that converting bool to int gives the expected values 0 or 1.
In Java and C#, you can use the following construct:
if ((a?1:0) + (b?1:0) + (c?1:0) + (d?1:0) == 3)

max value of integer
... in hex, because of the overflow (and equals to Integer.MIN_VALUE). If you convert it to unsigned (long), the sign bit will be treated like a value bit, so it will be 2147483648. Thank you for the char note. char is unsigned, you're right, but char is not really used for calculations, that's why I...
