I refer to this as the TULIP INDEX.
Take anything real and divide it by anything imaginary and you will approximate the TULIP INDEX. The real part of anything imaginary is ZERO. Therefore real divided by imaginary results in a pole (aka a singularity). Since there is no imaginary component of real the imaginary denominator goes into the imaginary portion of the numerator zero times. But mathematicians are convinced that zero divided by zero results in a one (nothing from nothing equals something).
Where the confusion results is when you try to divide the real component of the numerator by the imaginary component of the denominator. Like only joins with like so the result of this division is NONSENSE as you are attempting to discover how many times imaginary can be subtracted from real.
This is what I call the TULIP INDEX.
