Final answer:
IEEE 754 is the encoding that guarantees every value to be an integer.
Step-by-step explanation:
The IEEE encoding that guarantees every value to be an integer is IEEE 754. This is a standard for floating-point arithmetic in computer programming. The IEEE 754 encoding includes several formats, such as single-precision and double-precision, that represent floating-point numbers as binary values. In these formats, integers can be represented exactly without any loss of precision.
