fuzzyCompare

Compares two floating point values and returns true if they are considered equal, false otherwise

Compares two floating point values and returns true if they are considered equal, false otherwise. Inspired by Qt's qFuzzyCompare function. Two floating point variables that should in theory be equal, might not always be equal, due to mthe finite number of bits that a computational device uses to store and operate on values.

Ex:
num = 7;
sqrtd = sqrt(num);
sqrtd(2) = sqrt(sqrtd(1));
sqrtd(3) = sqrt(sqrtd(2))
prods(1) = sqrtd(end);
prods(2) = prods(1)^2;
prods(3) = prods(2)^2
finalNum = prods(3)^2
num==finalNum %This is false, though they should be the same
fuzzyCompare( num, finalNum ) %this is true
