conditional rounding

[Guest]

My current formula is =ROUNDDOWN(AB15/$AB$36,0). I want to change it to = 0
if it's zero. If the number is between .1 to .9 i want it to equal 1. If it's
greater than 1 I want it to round down. Can u help me?

=IF(AB15/AB36=0,0,IF(AND(AB15/A36>=.1,AB15/Ab36<=.9),1,ROUNDDOWN(AB15/AB36,0))
