Important limitations
The fraction is an approximation capped at a denominator of 10,000. Repeating decimals may therefore be shown approximately.
Multiplying a decimal by 100
Enter 0.075 to obtain 7.5%, not 0.075%. A value of 1 represents 100% and a value above 1 legitimately produces more than 100%. The fraction is an approximation, while the percentage is the entered decimal scaled by 100. This conversion alone does not calculate a percentage change between two values.
