JSON e and JSON E
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 equivalently E
) is equivalent to "×10^". For example,
3.7e-5
= 3.7E-5
= 3.7×10-5 = 0.000037
Positive 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 sextillion
More details are available at the Wikipedia article on scientific notation.
The letter e looks a lot like the mathematical constant e (the 2.71828 thing) so languages usually let you use E instead. As shown by nandhp, it does the same thing as e.
