Missing fast way to enter numbers in scientific notation

[callegar]

in a normal scientific calculator pressing
1 / 2 E - 3
one gets an expression interpreted as
1/(2*10^(-3))
that is 500

In PalmCalc 2019, the best approximation of E is Exp, but pressing
1 / 2 E - 3 )
one obviously gets and expression interpreted as
1/2*10^(-3) that is 0.0005

This may appear a bit confusing to those using regular calculators where both Exp and an "E" to help entering numbers in scientific notation are provided. More so, becase "Exp" is not in the upper zone of the keyboard, but where "E" is generally found in regular scientific pocket calculators. Please, consider adding "E" to help quickly enter numbers in scientific notation and leaving out Exp, since one has already 10^x.
