C:\>Add1 3,400 3.400

de-de: 3,4 + 1 = 4,4
en-us: 3400 + 1 = 3401
en-gb: 3400 + 1 = 3401
nl-nl: 3,4 + 1 = 4,4
fr-fr: 3,4 + 1 = 4,4

de-de: 3400 + 1 = 3401
en-us: 3.4 + 1 = 4.4
en-gb: 3.4 + 1 = 4.4
nl-nl: 3400 + 1 = 3401
Is not a numeric value in fr-fr: 3.400

So this basically proves Garbage in Garbage out.
