Perform two successive binary operations on same input

[ttw]

On the hp50g, I've done this several way depending on the desired operations. Sometimes I do things like (assuming two operands on the stack):
MAX LASTARG MIN
In other cases:
DUP2 "ops leaving single result" UNROT

I often need things like IDIV2 but that's so slow that IQUOT (or even / FLOOR) and MOD with LASTART or DUP2 are much faster.
