(no subject)

[swestrup]

Just coughed myself awake after only 4 hours sleep. Had to tell _sps_ that I still too sick to go see X2. It sucks to be me.

One small good thing is that the copy of the Mathematica manual that I ordered arrived yesterday. 1400+ pages. I guess Math is a big subject. The first two features I looked for (graphing of relations and calculations with signifigant digits) are not directly supported, although it looks like they are each only a day or so's work to add in since there are very closely related features in there already.

Calculations are indeed done with significant digits; the problem is that the default decimal input notation is hijacked by machine floats. But if you use the ` suffix you get the native (precision-tracked) floats. See sections 3.1.4 and 3.1.5....
