2019年10月1日 · That is, if you believe that log() is treating binary double precision exp(1) specially to get exactly 1.0, then it follows that there would have to be some other binary double precision number different from exactly 1, call it L, such that exp(L) is closer to binary double precision exp(1) than exp(1) gets.

2012年7月29日 · If you mean numeric base, in the same sense that Hexadecimal representation is base 16 number system, then use base2dec and dec2base. If you mean log base then log12(x) = log9(x).^(9/12) Sign in to comment.

Y = log(X) returns the natural logarithm ln(x) of each element in array X. The log function’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally. For negative and complex numbers z = u …

2018年4月15日 · Note that very few programming languages use log() to indicate log base 10. Excel is the only one I have been able to find. log() or Log[] seems to represent natural log in nearly all languages. As mentioned Excel uses log for base 10 by default; it has no built in natural log, requiring that a decimal approximation of e be passed as the second ...

2021年10月2日 · I saw that calculating log of the base of 10 or e is possible. for an example: after typing log (a,b) - I recieve an ERROR message. I'd like to use "a" as a varying number and change it using a loop until I'll get a good result. "a" can be for an example - 1.05, 1.003....

log: Natural logarithm: log10: Common logarithm (base 10) log1p: Compute natural logarithm of 1+X accurately for small X: log2: Base 2 logarithm and floating-point number dissection: nextpow2: Exponent of next higher power of 2: nthroot: Real nth root of real numbers: pow2: Base 2 exponentiation and scaling of floating-point numbers: reallog

2014年9月26日 · Hi peoples, how change the base of the log example: log9(9) = 1

Examine several values of the base 10 logarithm function. Calculate the common logarithm of 1.

2015年12月9日 · I would say that as a numeric system that is base 10, the default base for log() should also be base 10. But that's more of an opinion than a standard. And I know I can create an alias for ln() which leads to log(), but the bigger issue is the misuse of log() as log10().

The log() function is base-e log. So, to take log of x [mathematicians would usually say ln(x)], just do
