Examples: bubblesort | mandelbrot | number-to-ascii | strings
Convert number to ASCII, return pointer to static buffer.
var ntoa_buf::100; ntoa(x) do var i, k; if (x = 0) return "0"; i := 99; ntoa_buf::i := 0; k := x<0-> -x: x; while (k > 0) do i := i-1; ntoa_buf::i := '0' + k mod 10; k := k/10; end if (x < 0) do i := i-1; ntoa_buf::i := '-'; end return @ntoa_buf::i; end
