You can use ceil (ceiling). It only rounds up, so you'll have to multiply with 10000, do the ceil and then divide the result again.

EDIT: wait, wut? that doesn't work. I mean FLOOR obviously but the working is the same :D The manual is on the same page too :)

So floor(0.000145* 10000) = floor(1.45) = 1 Divide back and you'll have 0.0001
