Solved thanks to your response. Here's what I ended up using (keeping in mind,
mode=0 means idle, 1 means heating, 2 means cooling):
# automatically round up or down
CDEF:mode_rounded=mode,1,%,0.5,GE,mode,CEIL,mode,FLOOR,IF
CDEF:heating=mode_rounded,1,GE,temp,UNKN,IF
CDEF:cooling=mode_rounded,2,GE,temp,UNKN,IF
CDEF:heating_percent=mode_rounded,1,GE,100,*
CDEF:cooling_percent=mode_rounded,2,GE,100,*
VDEF:heating_percent_vdef=heating_percent,AVERAGE
VDEF:cooling_percent_vdef=cooling_percent,AVERAGE
