rpn.zip 1.5 2019-01-16 7.0 Salman Halim New commands:

c: clear the stack
f: print the entire stack
p: display the last entry on the stack (done by default at the end, anyway)
k: set precision (number of decimal places)
K: push the precision onto the stack
!: replace the item with its negative value
Z: replace the item with the number of characters it takes up (number of digits plus decimal point and negative sign)
z: push the size of the current stack
x: remove the entry (pop and destroy)

New special:

tax: Equivalent to multiplying by g:Rpn_taxRate. For example, if you set g:Rpn_taxRate to 1.5, then executing 'Rpn 3 tax' is the same as 'Rpn 3 1.5 *' -- I use it for sales tax calculations
