How floating point numbers are stored in computers In C and C # languages, float and double types are used for data of the floating point type for storage. float data occupies 32 bits and double data occupies 64 bits, how do we allocate memory when declaring a variable float F = 2.25f? If it is randomly allocated, isn't the world a mess? In fact, both float and double storage methods comply with IEEE specifications, Float complies with IEEE r32.24, wh
