It's just a precedence issue -- '_' has precedence over binary '-' or '+' but it should NOT have precedence over unary '-'. For temperatures things are bit more complex because of the additive constant. See the HP48 User Manual Pg 10-11 for a description of one (IMHO sensible) solution. But your specific example doesn't make sense to me. The answer to 5_°F+13_°F▶_°C is that it's an error since ▶ is simply a macro for CONVERT and 5_°F+((CONVERT(13_°F,0_°C)) won't parse. This has nothing to do with the expected behavior of -13_°F▶_°C |
