Given a number x, return the value that is closest to x from this list of constants: 0, 1, , e, π, (also known as τ).

For example:

c = closestconst(1.5)

c =

1.4142

c = closestconst(2.5)

c =

2.7183

c = closestconst(50)

c =

6.2832

c = closestconst(-10)

c =

0

If x is equally close to two values (eg ), you can return either value (so either 1 or would be correct in this example).
