What exactly does big Ө notation represent?
...ound.
Theta(g(n)) = { f(n) : there exists positive constants c1,c2 and n1 such that
0<=c1(g(n))<=f(n)<=c2(g(n)) for all n>=n1 }
when we say f(n)=c2(g(n)) or f(n)=c1(g(n)) it represents asymptotically tight bound.
O(n): It gives only upper bound (may or may not b...

How to compare two floating point numbers in Bash?

numCompare() {
awk -v n1="$1" -v n2="$2" 'BEGIN {printf "%s " (n1<n2?"<":">=") " %s\n", n1, n2}'
}
And call it as:
numCompare 5.65 3.14e-22
5.65 >= 3.14e-22
numCompare 5.65e-23 3.14e-22
5.65e-23 < 3.14e-22
