Since lists are just a particular kind of expression, it will come as no surprise that you can refer to parts of any expression much as you refer to parts of a list. This ...

RandomReal[] gives a pseudorandom real number in the range 0 to 1. RandomReal[{x_min, x_max}] gives a pseudorandom real number in the range x_min to x_max. RandomReal[x_max] ...

RandomInteger[{i_min, i_max}] gives a pseudorandom integer in the range {i_min, i_max}. RandomInteger[i_max] gives a pseudorandom integer in the range {0, ...

When you do calculations with arbitrary-precision numbers, Mathematica keeps track of precision at all points. In general, Mathematica tries to give you results which have ...
