Technical Information
Fraction Calculations
Example 1: 23 + 15 = 1315
- 2315
Example 2: 314 + 123 = 41112
- 314123
Example 3: 12 + 1.6 = 2.1
- 1216
- 2.1
Note
Values are displayed in decimal format automatically whenever the total number of digits of a fractional value (integer + numerator + denominator + separator marks) exceeds 10.
Results of calculations that mix fraction and decimal values are always decimal.
Decimal ↔ Fraction Conversion
To switch a calculation result between fraction and decimal format:
Press .
Example 1: 2.75 = 234 (Decimal → Fraction)
- 275
- = 114 (d/c)
Example 2: 12 ↔ 0.5 (Fraction ↔ Decimal)
- 12
Mixed Fraction ↔ Improper Fraction Conversion
To switch a calculation result between improper fraction and mixed fraction format:
Press (d/c).
Example 1: 123 ↔ 53
- 123
- (d/c)
- (d/c)
Note
You can use the display setup (Disp) screen to specify the display format when a fraction calculation result is greater than one.
To change the fraction display format, press the key a number of times until you reach the setup screen shown below.
Display the selection screen.
(Disp)
Press the number key ( or ) that corresponds to the setting you want to use.
(ab/c): Mixed fraction
(d/c): Improper fraction
An error occurs if you try to input a mixed fraction while the d/c display format is selected.
