  GoCalc -- a Gopher Calculator

  Uses bc(1) ; calculates to 4 significant figures *

  Supported math functions:  + - * /  ^  sqrt(expr)
                             l(n) = l(n)  log
   for Pi use 3.1418 ;       e(n) = ln(n) natural log
   180 deg = Pi radians      s(x) = sin(x) ; x in radians
    60 deg = Pi/3            c(x) = cos(x) ; x in radians
    30 deg = Pi/6            a(x) = tan(x) ; x in radians
  
     ex.  sqrt(3^2 + 4^2) => 5.0000 
              s(3.1418/6) =>  .5000  ( sine 30 deg )
                     e(1) => 2.7182  ( ln(1) )

   * change with 'scale=n;(math expr)' ; n = # sig figs
