•
On a Casio calculator you can enter a decimal point
•
Example 1
To calculate 
1 a b/c 2 + 1 • 6 = 1┘2+1.6
2.1
Results of calculations that mix fraction and decimal values are always decimal.
Example 2
To calculate sin (½π) = 1
sin • 5 EXP = sin .5π
1.
Example 3
To calculate 101.25
log 1 • 2 5 = 10 1.25
17.7827941
Example 4
To calculate sin-1(0.56) = 0.5943858
sin • 5 6 = sin-1.56
0.5943858
Example 5
To convert rectangular coordinates (1, 1.739) to polar coordinates (r, θ) enter two values, separated by a comma
Pol( 1 ❜ 1 • 7 3 9 ) = Pol(1,1.739)
2.006021186
Example 6
To convert 2.75 to the improper fraction
2 • 7 5 = 2.75
2.75a b/c 2.75
11┘4.

Example 7
To convert an angle of 4.25 radians to degrees
4 • 2 5 Ans D R G
1 2 32 4.25r_
= 4.25r
243.5070629
The standard setting for angles must be on degrees.
Example 8
To convert 0.08125 grams to milligrams
0 • 0 8 1 2 5 = ENG 0.08125
81.25×10-03
Example 9
To convert the decimal value 2.258 to the sexagesimal value 2° 15' 28" 8
2 • 2 5 8 = 2.258
2.258° , ,, 2.258
2°15°28.8
Example 10
To calculate 0.5√2 = 21/0.5 = 22 = 4
• 5 ∧ 2 = .5x√2
4.
Display format
There are many countries where decimal point and comma are used differently. You can change the display settings for decimal point and comma. The function of the keys stays unchanged, so it is not wise to do this.
