In a 32 bit processor if I want to access 8 bit or 16 bit data from RAM, how do processor manage?
Does it access 4 bytes and disposes remaining three?
Note: This is regarding ARM processor.
Please let me know.

Well, it doesn't 'dispose' of the data, you just 'mask off' what you don't need.
For instance, on intel processors, the register 'eax' can be accessed by:
[ al ][ ah ]
[ <-- ax -->]
[ <-------- eax ---------> ]
[byte][byte][byte][byte]
Of course I don't know 'for sure' that it can't access a single byte, just assuming there.
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
