This is the Euler-Mascheroni Constant 
(http://mathworld.wolfram.com/Euler-MascheroniConstant.html), and is denoted 
by a gamma or as C:

const float C = 0.5772156649015328606065120900824024310422F; // 
Euler-Mascheroni constant

So would I. The Euler constant has the value
   e = 2.718281828459045235360287471352662497757...
