Action
Draw a decimal number.
Syntax
CmdNumber x, y, font, options, n
Remarks
x |
x-coordinate of text base, in pixels |
y |
y-coordinate of text base, in pixels |
font |
font to use for text, 0-31. See ROM and RAM Fonts |
options |
By default (x,y) is the top-left pixel of the text. OPT_CENTERX centers the text horizontally OPT_CENTERY centers it vertically. OPT_CENTER centers the text in both directions. OPT_RIGHTX right-justifies the text, so that the x is the rightmost pixel. By default the number is displayed with no leading zeroes, but if a width 1-9 is specified in the options, then the number is padded if necessary with leading zeroes so that it has the given width. If OPT_SIGNED is given, the number is treated as signed, and prefixed by a minus sign if negative. |
n |
The number to display, either unsigned or signed 32-bit. NOTE : while -2147483648 is valid for a long, the FT800 will show -18446744071562067968 (128 bit signed number) which seems a bug in the FT800. |
