sprintf('%.2f00', round(N * 100) / 100)
Though I admit to being puzzled as to why you want the misleading '00' at the end, why you want 0.2400 instead of 0.24

If you want it just for displaying, what about:
sprintf('%.3f\n', [0.2371, 0.4546])
I'd definitly omit the trilaing zero, because it is not only confusing, but wrong.
