Fixed point logarithm

WebIn my opinion the answer above is not well structured. Point 4 describes the problem, the reason why you want to look for a smarter solution than just calculating the likelihood. Point 3 describes why you are even allowed to use the natural logarithm as a function because it keeps intact one important property of the original function. WebMar 25, 2024 · You're adding 18 trailing decimals to represent fixed-point numbers in your algorithm. for instance, you'd represent 0.5 as 500000000000000000, equivalent to 5e17 in scientific notation. Now, say you want to calculate the integer part of the binary logarithm of a number x that adheres to the format above.
