If the assignment is made, the result variable forces the mandatory conversion of the value, such as int i = 0.0 1, and the result is i==0.

Floating point type, float I = 0.00101->; 0.00 1 This operation first takes the decimal place * 1000 and assigns it to a long integer, then divides it by 1000.0 and assigns it to a floating-point number.
