WebDec 7, 2024 · 1 Answer Sorted by: 0 Floating-point numbers on computers are problematic only because of the effects of their limited numbers of binary digits of precision and the limited range of exponents, leading to roundoff errors, underflow, overflow, and other such problems. WebNot every decimal number can be expressed exactly as a floating point number. This can be seen when entering "0.1" and examining its binary representation which is either slightly smaller or larger, depending on the last bit. Other representations: The hex representation is just the integer value of the bitstring printed as hex.

WebScenario: In a biased N-bit binary number system with bias B, positive and negative numbers are represented as their value plus the bias B.
