Add more constants #5

Open JJ opened 7 years ago

JJ commented 7 years ago

Add a mathematical or physical constant with its corresponding test.

As long as you are adding new constants, here are some I didn't see and would like to:

--Artin's Constant https://oeis.org/A005596 --Base of the natural logarithm https://oeis.org/A081368 --Bernstein's Constant https://oeis.org/A073001 --Degree https://oeis.org/A072097 --Euler's Constant https://oeis.org/A002852 --Gelfond-Schneider Constant https://oeis.org/A078333 --Landau-Ramanujan Constant https://oeis.org/A064533 --Mandelbrot Set Area https://oeis.org/A098403 --Merten's Constant https://oeis.org/A077761 --Pi https://oeis.org/A000796 --Pythagora's Constant https://oeis.org/A322641 --Silver Ratio https://oeis.org/A014176 --Twin prime Constant https://oeis.org/A065645 --Zeta Function, Zeta(2) https://oeis.org/A013661 --i^i https://oeis.org/A049006

I've added the OEIS page for each. With those like Pi, Degree, 'e' etc., I may not have looked in the right place?

hi @hsmyers --- fwiw pi(π) and e(𝑒) are already built in terms in raku (https://docs.raku.org/language/terms) --- and there is some support for Degree over at Physics::Measure

#Angles use degrees/minutes/seconds or decimal radians
    my $θ1 ♎️ <45°30′30″>;      #45°30′30″ (using <> to deconfuse quotation marks)
    my $θ2 ♎️ '2.141 radians';  #'2.141 radian'
#NB. The unit name 'rad' is reserved for the unit of radioactive Dose

# Trigonometric functions sin, cos and tan (and arc-x) handle Angles
    my $sine = sin( $θ1 );      #0.7133523847299412
    my $arcsin = asin( $sine, units => '°' ); #45°30′30″
#NB. Provide the units => '°' tag to tell asin you want degrees back

Kinda thought they might be. Good to know where they 'live' though—thanks @ p6steve!
