 Return lowercase version of s.
std::string toUpper (const std::string &s)
 Return uppercase version of s.
String representation of number.
Optional second argument sets the minimal string width (' ' padded).

Negative values will cause the number to be left adjusted within the string.

Default width is 0. 

 numstring(42)           -> "42"

std::string numstring (unsigned long long n, int w=0)
String representation of number as hex value with leading '0x'.
Optional second argument sets the minimal string width (0 padded).

Negative values will cause the number to be left adjusted within the string. Default width is 10 (4 for char).

std::string hexstring (unsigned long long n, int w=0)
String representation of number as octal value with leading '0'.
Optional second argument sets the minimal string width (0 padded).

Negative values will cause the number to be left adjusted within the string. Default width is 5 (4 for char).
