#X text 11 78 WHAT IS A FLOATING POINT NUMBER?;
#X text 41 267 The following are examples of floating point numbers:
;
#X text 61 293 3;
#X text 62 334 -111.5;
#X text 61 313 0.5;
#X text 40 387 3e-05 : This example is a computer shorthand for scientific
notation. It means 3*10-5 (or 10 to the negative 5th power multiplied
by 3).;
#X text 41 108 According to Webopedia.com \, "computers are integer
machines and are capable of representing real numbers only by using
complex codes." 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.;

which sets value that is stored.;
