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.; -- cgit v1.2.1
