Can cause issues if you are accounting for things, e.g.
"The sum of these values need to equal the sum of these values"
In that case you'd then needs to avoid
"sum_a == sum_b"
and use instead
"abs(sum_a - sum_b) < SOME_SMALL_VALUE"
"The sum of these values need to equal the sum of these values"
In that case you'd then needs to avoid
"sum_a == sum_b"
and use instead
"abs(sum_a - sum_b) < SOME_SMALL_VALUE"
Not to mention that there is a use case for auditing pricing models (as in external requirement, or internally) or comparing alternative models.
