You can use sprintf or snprintf if available. Something like this.

Code: Select all

char temp[3];
sprintf(temp,"%02u");
Ogre::String str(temp);

C++ probably has another way also.

Also see StringConverter::ParseInt

parseInt is not from string to int?

i need inverse

from int to string

maybe i need this
static String Ogre::StringConverter::toString ( int val,
unsigned short width = 0,
char fill = ' ',
std::ios::fmtflags flags = std::ios::fmtflags(0)
)

with width=1 and char fill='0'

Like this, simply?

Code: Select all

int i = 3 ;
Ogre::String a = digit(i) ; // will return "03"

Ogre::String digit( int i , int n = 2 )
{
	// if you need 3 digits like "002" call digit(i,3);

	Ogre::String r = Ogre::StringConverters::toString(i) ;
	while( r.length() < n )
	{	r = "0" + r ;
	}	
	return r ;
	
}
