test-mp-equation: add tests for physical constants

It was necessary to change the test() function as well, in order to have
variable trailing_digits size. Otherwise most constants would be shown as zero.
So there is a "#define test(X, Y, Z) Test(X, Y, Z, 9)". Now test() works
with trailing_digits size 9, and Test() with a variable trailing_digit size.
