These examples use the OLD, NEW %CHG (percent change) and TOTAL, PART, %TOT (percent of total) keys on the Percentages Calculator
The OLD, NEW and %CHG are an expansion of the Δ% key found on many calculators. The Δ% key will only calculate the percent change given the old and new values. These keys will calculate any of the values given the other 2 values.
The TOTAL, PART, %TOT are an expansion of the %T key found on many calculators. The %T key will only calculate the percent of total given the total and part values. These keys will calculate any of the values given the other 2 values.
These keys use the CALC 1 Auto Sto feature.
Pressing shift then "C pct" will clear all of the percentage values to 0.
