Hello, speaking of the CEILING and FLOOR functions.
In UNICODE times, it would be great if we could code in RPL with the real math symbols.
-3.8 CEILING or
-3.8 ⌈⌉ [enter] -3
-3.8 ⌊⌋ [enter] -4
{ 1,2,3} {3,4,56} ∩ [enter] 3

PHP Code:

CEILING, ⌈⌉
FLOOR,  ⌊⌋
+ (sum)
- (subtraction)
×, * (multiplication)
÷, / (division)
^, ** (power)

Logical op

AND, ∧(conjunction) 
OR,  ∨ (disjunction)
NOT, ¬ (negation) 

relational OP
== (equal)> 
≠, !=, <> (different)
