Here are four famous numerical constants, extended to 50 decimal places: π, e, γ, and √2. For each constant, the approximation will be listed and a histogram of each of the 50 decimal places and the integer part (51 digits in total) will be presented.

Of the four constants presented, √2 has the most even distribution, at far as the first 50 decimal points are concerned.
Fun Fact: 99/70 gives √2 accurate to four decimal places.
99/70 = 1.41428 571428...
