7029 * We can approximate e^x by a Taylor/Maclaurin series (see
7030 * https://en.wikipedia.org/wiki/Taylor_series#Exponential_function):
7031 * @code{.unparsed}
7032 * n 0 1 2 3 4

7034 * SUM ----- = --- + --- + --- + --- + --- + ...

7036 *
7037 * 2 3 4
7038 * x x x
7039 * = 1 + x + --- + --- + --- + ...
7040 * 2! 3! 4!
7041 * @endcode
7042 *
7043 * Given z = x * ln2, we get:
7044 * @code{.unparsed}
7045 * 2 3 4 n
7046 * z z z z z
7047 * e - 1 = z + --- + --- + --- + ... + ---
7048 * 2! 3! 4! n!
7049 * @endcode
7050 *
7051 * Wanting to use Horner's method, we move one z outside and get:
7052 * @code{.unparsed}
7053 * 2 3 (n-1)
7054 * z z z z
7055 * = z ( 1 + --- + --- + --- + ... + ------- )
7056 * 2! 3! 4! n!
7057 * @endcode
7058 *
7059 * The constants we need for using Horner's methods are 1 and 1 / n!.
7060 *
7061 * For very tiny x values, we can get away with f(x) = x * ln 2, because
7062 * because we don't have the necessary precision to represent 1.0 + z/3 + ...
7063 * and can approximate it to be 1.0. For a visual demonstration of this
7064 * check out https://www.desmos.com/calculator/vidcdxizd9 (for as long
7065 * as it valid), plotting f(x) = 2^x - 1 and f(x) = x * ln2.
7066 *
7067 *
7068 * As constant accuracy goes, figure 0.1 "80387 Block Diagram" in the "80387
7069 * Data Sheet" (order 231920-002; Appendix E in 80387 PRM 231917-001; Military
7070 * i387SX 271166-002), indicates that constants are 67-bit (constant rom block)
7071 * and the internal mantissa size is 68-bit (mantissa adder & barrel shifter
7072 * blocks). (The one bit difference is probably an implicit one missing from
7073 * the constant ROM.) A paper on division and sqrt on the AMD-K7 by Stuart F.
7074 * Oberman states that it internally used a 68 bit mantissa with a 18-bit
7075 * exponent.
7076 *
7077 * However, even when sticking to 67 constants / 68 mantissas, I have not yet
7078 * successfully reproduced the exact results from an Intel 10980XE, there is
7079 * always a portition of rounding differences. Not going to spend too much time
7080 * on getting this 100% the same, at least not now.
