-#X text 10 436 High-performance computation requires precise and quite
-peculiar definitions of numbers and their representation.;
-#X text 10 486 Inside most programs \, numbers are written down as
-strings of bits. A bit is either zero or one. Just like the decimal
-system uses units \, tens \, hundreds \, the binary system uses units
-\, twos \, fours \, eights \, sixteens \, and so on \, doubling every
-time.;
-#X text 540 436 One notation \, called integer allows for only integer
-values to be written (no fractions). when it is unsigned \, no negative
-values may be written. when it is signed \, one bit indicates whether
-the number is positive or negative. Integer storage is usually fixed-size
-\, so you have bounds on the size of numbers \, and if a result is
-too big it "wraps around" \, truncating the biggest bits.;
-#X text 540 546 Another notation \, called floating point (or float)
-stores numbers using a fixed number of significant digits \, and a
-scale factor that allows for huge numbers and tiny fractions at once.
-Note that 1/3 has periodic digits \, but even 0.1 has periodic digits
-\, in binary coding \; so expect some slight roundings \; the precision
-offered should be sufficient for most purposes. Make sure the errors
-of rounding don't accumulate \, though.;
