The problem was that when converting a string to an exact number, rounding didn't work, because conversion didn't understand approximate numbers notation. Fix: a new function for string-to-number conversion was implemented, which is aware of approxinate number notation (with decimal point and exponent, e.g. -19.55e-1)
