//***********************************************************************************
//* == Floating Point Comparison == *
//* *
//* Naturally JS stores all numbers (real/complex/rational/ect...) as floating *
//* points, this is good and bad. *
//* *
//* Good: { *
//* - No type conversion *
//* - More percise calculations *
//* } *
//* *
//* Bad: { *
//* - Less control over data types *
//* - You have to design these comparisons *
//* - Slower to process (JS remains very fast though) *
//* - Harder to deal with *
//* } *
//***********************************************************************************
// Call the function and ask for the three parameters.
function compare(numb1, numb2, offset) {
var tmp; // Declare a temp to be assigned and compared to the allowed offset.
// Subtract the two vales (Math.abs(x - y); may work but this is safer.)
(numb1 < numb2) ? tmp = (numb1 - numb2) : tmp = (numb2 - numb1);
return tmp < offset;
