this is the "natural", or base-e log,
When
e%5Ey+=+x
Then base e logarithm of x is
ln%28x%29+=+log_e%28x%29+=+y


The e constant or Euler's number is:
e+=+2.71828183

ln%28200%29=5.2983173665480366774532150308269049832777031116178012

ln%28200%29=5.3............rounded to one decimal place

so, 2.71828183%5E5.2983173665480366774532150308269049832777031116178012=200.0000
