reference like you can with pointers There 䏭 no 禃eference arithmetics but you can take the address of an object pointed by a reference.. address of an object pointed by a reference and do pointer arithmetics on it as in obj 5 . because as you commented you have doubt..

Float addition promoted to double?

reasons it would make sense to perform all floating point arithmetics in double precision before converting the result to single precision...

Fast bignum square computation

http://stackoverflow.com/questions/18465326/fast-bignum-square-computation

possible without precision loss using C and with integer arithmetics 32bit with Carry at disposal. My current aproach is applying.. field DFT and so no accuracy loss occur need of modular arithmetics on unsigned integers modpow modmul modadd modsub i use DWORD.. is limited because of overflow issues For 32bit modular arithmetics is N limited to 2^32 max input ^2 so bigint must be divided..
