The rule with a comparison sign less than ("<") constant does not work, but with a comparison sign less than or equal to ("<=") works

Description

Example of a working rule:

(rule "Constrain drill slots"
	(constraint disallow pad)
	(condition "A.Hole_Size_X != A.Hole_Size_Y && A.Hole_Size_X <= 0.49999mm")
)

Example of a non-working rule:

(rule "Constrain drill slots"
	(constraint disallow pad)
	(condition "A.Hole_Size_X != A.Hole_Size_Y && A.Hole_Size_X < 0.5mm")
)

Steps to reproduce
