- written to files and to windows. (however #in converts to int32 unless otherwise specified.);

-#X text 10 416 High-performance computation requires precise and quite peculiar
- definitions of numbers and their representation.;
-#X text 10 476 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 10 536 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 10 596 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.;
