Is there such things as half stop or 1 n half stop?

hi,

when developing, is there such things as push 1 n half stop?
Say when I set an 100 film on ISO320. So I ask for an 1 n half push?

thanks

technically should be no problem.

But dun u think life is alot easier if u push 2 stops instead of 1½?

there is,pust 1 stop is to add the developing time by 33% of the original developing time,1 1/2 stop means first add 33% than add another 20% ontop of the total time.
