ex
On a Casio calculator you can calculate powers of the number e
ln
Example 1
To calculate e0 = 1
ln e_
0.0 = e0
1.
Example 2
To calculate e1 = 2.7182…
ln e_
0.1 = e1
2.718281828
or show the value directly with
ln e_
0.= e
2.718281828
Example 3
To calculate eπ = 23.140…
ln EXP = eπ
23.14069263
Example 4
To calculate ln (e2) = 2
ln ln 2 = ln e2
2.
Example 5
To calculate e(− π / 2) = 0.207879576...
ln ( (−) EXP ÷ 2 = e(-π÷2)
0.207879576
Details
The functions ln, ex and e are on the same key. That is logic as the functions all have to do with the number e.
