I've been experiencing this issue which doesn't really make sense. I'm trying to generate a constant of 2.55 using a an using fixdt(0,8,0.01,0) slope (expected 255 / 255 Value) but the Representable maximum: 2.5500000000000003 in the propriety of the constant. Same situation apply when using a 16 bit with the 0.0001 resolution... When trying to execute the diagram i'm getting the error "Inconsistent numeric values for parameter 'Value' in maxRoundingIssue/Constant_8bit': Quantized parameter value (2.5500000000000003) is greater than maximum (2.55)"

Have a look at the screenshot, is there something i'm missing?
