Underflow and overflow errors cannot be completely eliminated in computer arithmetic due to the inherent limitations in the representation of numbers. Computers use a finite number of bits to represent numbers, which inherently restricts the range and precision of values that can be represented.
Jun 15, 2011 · An underflow is basically the same thing happening in the opposite direction. The floating-point standard used for C allows for 23 bits after the decimal place; if the number has precision beyond this point it won't be able to store those bits. This results in an underflow error and/or loss of precision.
Underflows refer to floating point underflow, where an operation result in a number that is too small to be representable. For example, if the exponent part can represent values from $-127$ to $127$, then any number with absolute value less than $2^{-127}$ may cause underflow.

The binary number system is a base-2 numeral system that uses two symbols: Zero and one respectively. This system serves as the fundamentals of all the binary codes in use within the computer systems, especially in processing and storage of data. In this system that each binary digit (bit) stands for an increasing power of 2 from right to the left....
Overflow takes place when the result of the calculations exceeds the range of the number to be represented in a fixed number of bits with the help of 2’s complement format. Specifically, overflow happens under the following conditions:
Overflow occurs when: 1. Two negative numbers are added and an answer comes positive or 2. Two positive numbers are added and an answer comes as negative. Let us understand more in-depth. Consider the below scenarios, 1. If x & y are +ve numbers then x+y > max(x,y) 2. if x & y are -ve numbers then x+y < min(x,y) 3. If x is +ve and y is -ve then y< ...
This article has described the overflow conditions occurring in 2’s complement representation of signed integers. It explained the survey of binary number formation and its usage in computer architecture and defined the event of overflow when the outcome of addition exceeds N numbers. A brief explanation of overflow detection methods was provided, ...

Underflow and overflow are conditions in floating-point arithmetic that are indirectly related to rounding errors. They occur when the result of a computation is too small or too large to be represented within the range of the floating-point format being used.
