Min-max scaling uses exact feature endpoints from the displayed table.
Compute the small-feature range
For the small feature, min is 0, max is 4, so the range is 4.
Compute the large-feature range
For the large feature, min is 0, max is 100, so the range is 100.
100−0=100
Use the same rule per feature
Each displayed value uses value minus min over max minus min. The denominator is feature-specific and exact.
xscaled=max−minx−min
