Re: IntegerPart


There's nothing wrong with the IntegerPart function.
Use ListLinePlot instead of Plot:

ListLinePlot[prefstate, AxesOrigin -> {0, 0},
TicksStyle -> Directive[18], PlotStyle -> {Black}]

Cheers,
Dave Snead

can anyone help with this. There seems to be something wrong with the 
IntegerPart function. Please help!

Clear["Global`*"]
nSize = 100;

prefstate = Table[0, {i, 1, nSize}];
Do[
  {prefstate[[i]] = If[EvenQ[i], 0.8, 0.4]},
  {i, 1, nSize}
  ];

Plot[{prefstate[[IntegerPart[x]]]}, {x, 1, nSize + 1},
AxesOrigin -> {0, 0}, TicksStyle -> Directive[18],
PlotStyle -> {Black}]
