Maybe time for another coffee, but I am seeing a strange issue that I wasn't expecting to see.
I'm reading JavaScript The Good Parts and in the grammar section I am seeing the following:
If a number literal has an exponent part, then the value of the literal is computed by multiplying the part before the e by 10 raised to the power of the part after the e. So 100 and 1e2 are the same number.
From pg. 8 of JavaScript: The Good Parts by Douglas Crockford. Copyright 2008 Yahoo! Inc., 978-0-596-51774-8.
I'm I incorrect in thinking that 2e2 should equal 400?
According to the book, shouldn't this value be (2*10)^2?
In my console it is showing me 2e2 == 200.. Is my math, reading comprehension, or anything else off? Do I need to return to basic algebra?
Thanks in advance.
2e2 is interpreted as 2*(10^2) and not (2*10)^2. The former evaluates to 2 * 100 which equals 200. The latter evaluates to 20 ^ 2 which is why you are getting 400.
