196,940,000 entries; a math challenge

Feb 10.2004

Morning everybody. new to this forum. be gentle.

i’m having trouble setting up the math for this, and its prolly easier than i think.

i would like to create an array creator. where there is one array with 16,205 more arrays in it. and 12,153 entries within each of those. to start i’d like just a designation number to be in each of the 196 million plus spots and later i’ll write code to replace the number of the users choice with a name or something.

note: the idea for this website is to represent every square mile on the planet with a number, and display it in a 3×4 ratio

would it be easier to just create one long 196mil+ array and write seperate code for how its displayed?

also, can internet explorer even display a page with so may numbers on it? in the final version the table wont be displayed but i might want to try to see if my code is working.

@sydeffexauthorFeb 11.2004 — i appreciate the help ? to bad its way to slow to have practical use. how about some code that will determine which of the 16205 arrays and where in the 12153 entries of each array a users number (1-196940000) should be placed? that way the whole array wont have to be created before hand, just something that'll note which places are already taken.

i suppose you could do that by generating the name for the needed array bigArray[bigArrayNum16205[12153]] but it would take some crazy math to get the numbers right.

Success!
