Hello,

In order to prevent the global modification of mode() and ieee() user settings outside the
function, it would be nice coding this as follow:

mode_ini = mode()
mode(0)
ieee_ini = ieee()
ieee(1)
//... then, at the end, before quitting the function:
mode(mode_ini)
ieee(ieee_ini)

Thanks
Samuel
