NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.
This function may be more accurate than the mathematically-equivalent expression using the power function, such as pow(16.0, x).
Caution: Because the function grows rapidly for arguments of large magnitude, it approaches Infinity fairly quickly. Also, for arguments of small magnitude, exp16(x) - 1 suffers loss of leading significant digits; use the accurate exp16m1(x) function instead.
