◆ CompareNumbers()

static bool CompareNumbers ( const char *&  F1P,
const char *&  F2P,
const char F1End,
const char F2End,
double  AbsTolerance,
double  RelTolerance,
std::string *  ErrorMsg 
)

◆ EndOfNumber()

static const char * EndOfNumber ( const char Pos)
static

EndOfNumber - Return the first character that is not part of the specified number.

This assumes that the buffer is null terminated, so it won't fall off the end.
