Question

How do I extract roundUp(...) using regex (or some other derivative) from the following possible permutations:

[[[ roundUp( 10.0 ) ]]]
[[[ roundUp( 10.0 + 2.0 ) ]]]
[[[ roundUp( (10.0 * 2.0) + 2.0 ) ]]]
[[[ 10.0 + roundUp( (10.0 * 2.0) + 2.0 ) ]]]
[[[ 10.0 + roundUp( (10.0 * 2.0) + 2.0 ) + 20.0 ]]]

The reason I’m asking is I would like to replace roundUp(...) with math.ceil((...)*100)/100.0 in my code but I’m not to sure how to do it because of the chance brackets being used multiple times to help with operator precedence

Answer 1

This is python, why don’t you just rebind the name roundUp:

def my_roundup(x):
  return math.ceil(x*100)/100.

roundUp = my_roundup
