%, the output tax of a commodity is: 8000 * 17% = 1360 yuan.When purchasing a product, 60 yuan (tax-included) is paid for each item. The total amount is 100*60 = 6000 yuan (tax-included). The total value should be 6000/(1 + 17%) = 5128.21 yuan, Tax Amount: 5128.21 * 17% = 871.79 yuan.The new value of the above 100 items A is 8000-5128.21 (cannot be reduced by 6000

At present, the mainstream PowerPC processor manufacturers have IBM, Freescale™semiconductor (formerly Motorola Semiconductor Division), AMCC, LSI and so on. One of the most popular PowerPC processors is IBM and Freescale. This article on the two companies based on the PowerPC processor, started to tell the PowerPC family.
IBM's PowerPC family
IBM currently has a total of 3 major PowerPC processing series: Power, Power pc and cell. Power,power PC Center, there is also a

Part I: SenderThe first step in the program is to create a source in which we will open a window (or IFRAME, if you prefer) to send a message to another new window (for example, we will send a message every 6 seconds, Also create an event listener to listen for any responses we receive from the target window. )
The code is as follows
