How to normalize a mantissa

A floating point number is normalized when we force the integer part of its mantissa to be exactly 1 and allow its fraction part to be whatever we like. For example, if we were to take the number 13.25, which is 1101.01 in binary, 1101 would be the integer part and 01 would be the fraction part. I could represent 13.25 as 1101.01*(2^0), but this isn’t normalized because the … Read more

Standardize data columns in R

I have to assume you meant to say that you wanted a mean of 0 and a standard deviation of 1. If your data is in a dataframe and all the columns are numeric you can simply call the scale function on the data to do what you want. Using built in functions is classy. Like this … Read more

What does it mean to normalize a value?

It’s a mathematical term and this link explains its meaning in quite simple terms: Operations in 2D and 3D computer graphics are often performed using copies of vectors that have been normalized ie. converted to unit vectors… Normalizing a vector involves two steps: calculate its length, then, divide each of its (xy or xyz) components by its length…
