only use the greater N value to more accurately represent this number, That's why in many areas programmers prefer to use double instead of float.For the memory structure of float, I use a structure with a bit field as described below:struct Myfloat{BOOL Bsign:1; Symbol, positive or negative, 1-bitChar Cexponent:8; Index, 8-bitunsigned long ulmantissa:23; Mantissa, 23-bit};The symbol does not have to say more, 1 means negative, 0 means positiveThe in
