Fixed-point representation
Webin fixed-point numbers, the denominator is implicitly hardcoded in the software (that is, all code that deals with the numbers assume a fixed exponent/denominator) For example, 1.30 decimal is represented as 85196 / 65536 if the denominator is 2^16. The … WebOf course, the actual machine representation depends on whether we are using a fixed point or a floating point representation, but we will get to that in later sections. ... The floating point representation of a binary number is similar to scientific notation for decimals. Much like you can represent 23.375 as: \[2.3375 \cdot 10^1\]
