6 "IRIT Version 8.0" PRINTF PRINTF( StringType CtrlStr, ListType Data ) A formatted printing routine, following the concepts of the C programming language’s printf routine. CtrlStr is a string object for which the following special ’%’ commands are supported: %d, %i, %u Prints the numeric object as an integer or unsigned integer. %o, %x, %X Prints the numeric object as an octal or hexadecimal integer. %e, %f, %g, Prints the numeric object in several formats of %E, %F floating point numbers. %s Prints the string object as a string. %pe, %pf, %pg Prints the three coordinates of the point object. %ve, %vf, %vg Prints the three coordinates of the vector object. %Pe, %Pf, %Pg, Prints the four coordinates of the plane object. %De, %Df, %Dg, Prints the given object in IRIT’s data file format. All the ’%’ commands can include any modifier that is valid in the C programming language printf routine, including l (long), prefix character(s), size, etc. The point, vector, plane, and object commands can also be modified in a similar way, to set the format of the numeric data printed. Also supported are the newline and tab using the backslash escape character: PRINTF("\tThis is the char Backslashes should be escaped themselves as can be seen in the above example. Here are few more examples: PRINTF("this is a string list("STRING", 1987)); PRINTF("this is a vector [%8.5lvf]\n", list(vector(1,2,3))); IritState("DumpLevel", 9); PRINTF("this is a object %8.6lDf...\n", list(axes)); PRINTF("this is a object %10.8lDg...\n", list(axes)); This implementation of PRINTF is somewhat different than the ‐2‐ C programming language’s version, because the backslash always escapes the next character during the processing stage of IRIT’s parser. That is, the string ’\tThis is the char is actually parsed by the IRIT’s parser into ’This is the char ""0 because this is the way the IRIT parser processes strings. The latter string is the one that PRINTF actually see.
