Convert int to float

IntConversionChengFloat

1,Taking the integer part, there is a floating point coprocessor in computer computing, and the hardware can be switched. If there is no floating point coprocessor, software simulation is required..[1]

2. in C language, regardless of the expression value, the system automatically converts it to the type of the Left variable of the value assignment operator. [2]

3. The precision will be lost when converting from int to float, because the int is valid for 31 bits and the float decimal is valid for 23 bits. The double decimal point has a valid value of 52 digits. Therefore, the int type must be converted to a floating point. [3]
