Parses a real number and converts it to numeric type T
.
Matches a real number in the mathematical sense in C++ floating-point representation, and attempts to convert it to the type T
. If the real number cannot be converted to type T
then an std::range_error
is thrown, which is most likely caught by higher layers of the library and converted to an std::runtime_error
with additional information about the failure. The syntax is that which is recognized by the strtod
function, plus trailing white space.

Allocating constructor.
Returns a pointer to a new RealNumberParser object. Uses will most likely want to use the realNumberParser factory instead, which requires less typing.
