To return 1 if 'f' is 0.0 or -0.0. Returns 0 otherwise.


To return the +1 if the sign of 'f' is positive, or -1 otherwise.


To return the exponent (the X of 2^X) of the floating point 'f' from 'DENORMALIZED_POWER_OF_2' to 'INFINITE_POWER_OF_2'. To return the mantissa of 'f', with the HIDDEN_BIT or-ed in if 'f' is not denormalized. To return the 0x0 when given +1, or 0x1 when given -1.


To return the exponent field's bit pattern for power of 2 'powerOf2'. If 'powerOf2' is greater or equal to 'INFINITE_POWER_OF_2'


To return the mantissa _field_, 'mantissa' with its hidden bit turned off.


See which has the bigger power-of-2: 'f' or 'g' // Shift the smaller of the two by the difference in power of 2. // Then add the mantissas. // What is the value of 'powerOf2'? What is the value of 'sign'? // How do you detect when the mantissa overflows? // What do you do when the mantissa does overflow?
