If I understand your question right, this depends on whether you are in the US, or in Europe or some places in Asia. In the US, 63,500 is sixty three thousand and five hundred. In fact, most in the US don't even know it can have another meaning elsewhere in the world :). If you are in Europe, and some places in Asia, and I don't know where all else, this would be sixty three and a half. This caused quite a bit of controversy and contention when things computer standards were being hammered out across national borders. Because of this, there may be some differences from what I said above in some computerized applications, but just to add to the confusion, I don't think it is consistent across all applications as nationalization attempts to make things easier for people to read.

This number should be read as "Sixty three thousand, five hundred" in standard English, but "Sixty three point five thousand" is also accepted.

just sixty three thousand five hundred no and or point
