It took some painful debugging (the bug causes an infinite loop which the chrome/firefox debug tools do not handle well) but finally tracked it down. It is caused by a difference in the result of floating point division due to postscript's single-precision versus javascript's double-precision...
division". The only way of "fixing" this would be to remove that optimization, in which case the "/2" case would become about as slow as the "*.5" case. That's not what you want, is it? ;-) Background: All of this is due to JavaScript, where every number is a double. As...
which is a dedicated LTE network, TDD (Time Division Duplex) on Band 40, with 5G enabling technologies. Devices are connected to the network through either embedded modem (e.g., LTE enabled mobile phones) or using external USB modems, and the received data rates were measured to 70 Mbps ...
