	Common functions to work with integers and doubles.

Functions
std::string	Lox::Numbers::approximateSize (const uint64_t bytes)
	Returns a simple easy-to-read text string representing the number of bytes. More...
std::string	Lox::Numbers::format (const double &d)
	Format a double into a simple string. Will truncate trailing zeros. More...
std::string	Lox::Numbers::format (const double &d, const int decimals)
	Format a double into a simple string. Will truncate, pad, or round as necessary to the specified number of decimal places. More...
std::string	Lox::Numbers::format (const int &i)
	Format an integer into a simple string. More...
bool	Lox::Numbers::nearlyTheSame (const double a, const double b)
	Determine if the two values are nearly the same. More...
bool	Lox::Numbers::parse (const std::string &str, double &d, double &fraction)
	Parse a text string and get back the numeric value as a double. More...
bool	Lox::Numbers::parse (const std::string &str, double &d)
	Parse a text string and get back the value as a double. More...
bool	Lox::Numbers::parse (const std::string &str, int &i)
	Parse a text string and get back the value as an integer. This will round (not truncate) fractional values. More...
int	Lox::Numbers::random (const int minimum, const int maximum)
	Generate a random number. More...
int	Lox::Numbers::random (const int maximum)
	Similar to random( const int, const int ), but the minimum is set to zero. More...
double	Lox::Numbers::random (const double minimum, const double maximum=1.0)
	Generate a random number. More...
std::string	Lox::Numbers::reformatDoubleStr (const std::string &str)
	If the input string is a valid double, reformat the string. Make no change if the string is not a valid double. More...
std::string	Lox::Numbers::reformatIntegerStr (const std::string &str)
	If the input string is a valid integer, reformat the string. Make no change if the string is not a valid integer. More...
std::string	Lox::Numbers::reformatStr (const std::string &str)
	If the input string is a valid number, reformat the string. More...
bool	Lox::Numbers::validate (const std::string &str)
	Determine if the text is a valid number. Assumes "double". More...
bool	Lox::Numbers::validateDouble (const std::string &str)
	Determine if the text is a valid double. More...
bool	Lox::Numbers::validateInteger (const std::string &str)
	Determine if the text is a valid integer. More...
double	Lox::Numbers::round_to_2_decimals (double value)
	Round to 2 decimal places. More...
long double	Lox::Numbers::round_to_2_decimals (long double value)
	Round to 2 decimal places. More...
