[UPDATE] bugfix in code listing
The method for the radix conversion of floating point numbers described more theoretically here and more practically here has one large drawback: albeit always correct it is abysmally slow for large magnitudes.
The conversion of a string to a binary encoded floating point number is not easy, as shown in my last post. The information given there is a bit too much on the theoretical side. I’ll try to change that here with some real code: String to Bigfloat and Bigfloat to String. Continue reading →
The Little programming language is in need of arbitrary precision floating point numbers, too. The necessary basics at least: addition; multiplication; division; roots; logarithm; an exponential function; and the three basic trigonometric function sin, cos, and tan; not to forget the constant computed to the current precision. More to come, of course, but these are the minimum for a comfortable environment.
Well, that’s all fine and dandy but how do we get the numbers in and out? Yes, that’s not that simple, indeed. Continue reading →
