#X text 19 37 All numbers in Pd are kept in 32-bit floating point and
can represent real numbers between -8 \, 388608 and 8.388.608.00;
#X text 19 233 The following are examples of floating point numbers:

#X text 49 253 3;
#X text 50 294 -111.5;
#X text 49 273 0.5;
#X text 20 126 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 7 411 An Interesting Side-Note;
#X text 19 443 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 49 343 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).;
