Integer & Real/Float Conversion in C

Integer and float conversion

If you would like to develop an effective C program. Then you should understand/know about some rules for implicit conversion of integer and real/floating value in C language.

Important rules are defined below:-

1. When we would perform an arithmetic operation between an integer and an integer operation will always produce an integer result.

For ex. 1-    int + int = int;

          5 + 4 = 9;

2. When we would perform an arithmetic operation between a real and a real operation will always produce a real result.

    For ex. 2-    real + real = real;

              5.0 + 4.0 = 9.0;

3. When we would perform an operation between an integer and a real then this operation will always produce a real result. 

  For ex. 3-   int + real = real;

            5 + 4.0 = 9.0;

Process for example 3 - first integer will be promoted to a real constant/variable then this operation would be performed and result would be real.
