RPN scientific calculator firmware for $13 calculator kit

[toml_12953]

Is there a way to enter an exponent during number entry? I'd like to be able to enter scientific notation numbers. The only way I see to do it now is this

Example: Enter 1.67e14

1.67
Enter
14
Shift 6 (10^x)
*

That wouldn't be too bad if the base 10 antilog returned integers when given an integer argument but it doesn't always (as in the example above)
