WebJan 30, 2014 · You could look at IEEE 754 at the interchanging formats of floating points. But the key should be to define a network order, ex. 1. byte exponent and sign, bytes 2 to n as mantissa in msb order. Then you can declare your functions uint64_t htond (double hostdouble); double ntohd (uint64_t netdouble); WebThe suffix f or F (capital or small letter) is used at the end of the floating value. If no suffix is provided, the C++ compiler takes it as the Double type value. The float takes four bytes (or 32 bits) in the memory. The Double data type takes eight bytes (or 64 bits) Min Value = -3.4 E+38 (may differ) Max value = +3.4 E+38 (may differ)
