Zsolt, I hear what you are saying and generally agree, however we have been using calculations 'plagued by rounding errors' for centuries and our bridges are not collapsing. Such is a nature of a calculator, even scientific one.
there is a reason, why Math Java API or even Apache Commons Maths use doubles everywhere: http://download.oracle.com/javase/6/docs/api/java/lang/Math.html http://commons.apache.org/math/ The reason being speed and simplicity. Now looking at BigDecimal API (http://download.oracle.com/javase/6/docs/api/java/math/BigDecimal.html), how would you calculate say cube root of said BigDecimal or maybe any trigonometrical function? Right tools for right problems kind of thing...
