Subnormal numbers, also known as denormalized numbers, are floating-point numbers that fill the underflow gap around zero in the IEEE 754 standard. They allow for the representation of numbers smaller than the smallest normal floating-point number, providing a gradual underflow and maintaining precision in calculations involving very small numbers.

The IEEE 754 Standard is a widely adopted specification for floating-point arithmetic in computers, defining formats for representing and calculating with real numbers to ensure consistency and reliability across different computing systems. It covers aspects such as rounding, precision, and handling of special values like NaN (Not a Number) and infinity, facilitating interoperability and precision in scientific and engineering computations.
