I have a dumb question. Base on this code from CFA10097.INO,

Code:
        FWo=EVE_PrintF(FWo,
                         x_points[i]+xoffset,  //X coordinate
                         y_points[i]+yoffset,  //Y coordinate
                         27,                   //Font
                         EVE_OPT_CENTER,       //Options
                         "T[%d]@(%d,%d)",      //"printf" style format string
                         i+1,                  //point number displayed as text
                         x_points[i],          //X coordinate displayed as text
                         y_points[i]);         //Y coordinate displayed as text
How does one display a number with a decimal point? I tried:

Code:
 float temp_F;
 temp_F = 32.1;

 FWo=EVE_PrintF(FWo,
                50,  //X coordinate
                50,  //Y coordinate
                27,                   //Font
                EVE_OPT_CENTER,       //Options
                "Temp = %f Deg. F", temp_F);     //display text
When I run it, it displays "Temp = ? Deg. F"
ideas???
