Float numeric types are used to represent single-precision floating-point numbers, whereas double numeric types are used to represent double-precision floating-point values.float and double are floating point types, while decimal is fixed-point type;
Some time ago to hit the code found something about the type of float strange phenomenon, take it out and share with you.Run the following code on Linux:#include int main () {float a=16777216;float b=16777217;float c=16777218;float d=16777219;float
