Hence \, real numbers must be 'approximated' by computers +using the "floating point standard". In such a number \, the decimal +point can "float" meaning that there is no fixed number of digits preceding +or following the decimal. A floating point number is therefore a computer's +approximation of a real number.; +#X text 43 453 Interesting side-note: In the early 1990's \, the Intel +80486 was shipped with a math coprocessor to help accelerate the process +of computing floating point numbers (which previously required a considerable +amount of CPU power.) Math coprocessors have since found there way +into nearly every graphics card and CPU available today.; +#X text 62 358 10000 to 1e-016; +#X restore 114 534 pd More_Info; +#X text 158 561 - Dave Sabine \, November 18 \, 2002; +#X connect 2 0 13 0; +#X connect 3 0 13 1; +#X connect 5 0 13 0; +#X connect 6 0 13 0; +#X connect 8 0 14 0; +#X connect 12 0 13 0; +#X connect 13 0 4 0; +#X connect 14 0 7 0; -- cgit v1.2.1
