On the JSON website here, it explains the different possibilities of JSON ‘objects’. However, in the numbers section, these appear:
e | e+ | e- | E | E+ | E-
1 – What do these represent?
In searching for an answer, <E> appears alot.
2 – Is <E> related to the above e|Es?
It’s the notation JSON (and most programming languages) use for scientific notation. Scientific notation is used to denote very large or small floating-point numbers. The
e(or equivalentlyE) is equivalent to “×10^”. For example,3.7e-5=3.7E-5= 3.7×10-5 = 0.000037Positive or negative exponents may be used, and in the case of positive exponents, the
+symbol may be omitted:6.02e+23=6.02e23= 6.02×1023 = 602 sextillionMore details are available at the Wikipedia article on scientific notation.
