Stdlib
Stdlib
only exists as a header file, collecting all
the include
and using
statements that
are required by most other classes to access the C++
Stdlib
containers and methods.
In addition, the file contains inline functions pow2(x)
,
pow3(x)
, pow4(x)
and pow5(x)
,
for small integer powers, sqrtpos(x)
where a
max(0., x)
ensures one does not take the square root of
a negative number, and tolower(string)
that converts
a whole string to lowercase characters (extending on the
tolower
fuction for a single character).
