Is there any rationale for permitting three leading zeroes, but not four as long as the resulting numeric value is within range? It merely adds a few instructions to some code path while providing no benefit to anyone. I don't accept that performing the check on string length results in a greater time saving in iterations in the subsequent numeric conversion code.
