Frequently Asked Questions
Toggling Calculation Results
Each press of will toggle the currently displayed calculation result between its decimal form and fraction form.
Example 1: 1 ÷ 5 = 0.2 = 15 (MthIO-LineO)
- 15
- 0.2 15
Example 2: 1 ÷ 5 = 0.2 = 15 (LineIO)
- 15
- 0.2 15
Example 3: 1 - 45 = 15 = 0.2 (LineIO)
- 145
- 15 0.2
Important!
With certain calculation results, pressing the key will not convert the displayed value.
You cannot switch from decimal form to mixed fraction form if the total number of digits used in the mixed fraction (including integer, numerator, denominator, and separator symbols) is greater than 10.
Note
With Natural Display (MathO), pressing instead of after inputting a calculation will display the calculation result in decimal form.
