Trace Button and Decimal Precision (Quick Notes)

Trace button for filling the table

  • Hitting the trace button fills out the table to show what decimal the values are in.

Decimal precision rule

  • The decimal place is always half the smallest unit of measure.

  • Mathematically: precision increment=12×smallest unit\text{precision increment} = \frac{1}{2} \times \text{smallest unit}

Typical data resolution

  • Most data values are within tenths or hundredths; you usually don't need more precision than that.

  • Example: smallest unit = 0.1 ⇒ precision = 0.05
