FORMAT

This is the platform dependent conversion specifier for scanning and printing values of type int16 .

It is a string literal, but doesn't include the percent-sign, such that you can add precision and length modifiers between percent-sign and conversion specifier.

gint16 in;
gint32 out;
sscanf ("42", "%" G_GINT16_FORMAT, &in)
out = in * 1000;
g_print ("%" G_GINT32_FORMAT, out);

Example: printf, int16:

public static int main (string[] args) {
	// Output: ``10``
	int16 val = 10;
	print ("%" + int16.FORMAT + "\n", val);
	return 0;
}
