In arithmetic for reconfigurable computing designs, it is common to employ fixed point instead of floating point to represent scaled values. This chapter explores the reason for this design decision and the associated analysis that must be performed to choose an appropriate fixed-point representation ...
游戏中的帧同步要求的计算⼀致性——定点数（FixedPoint）最近做了⼀款帧同步游戏，其寻路算法采⽤了RVO算法。但是由于是移动端的游戏。需要在不同的设备上运⾏，其所有运算必须符合⼀致性——即所有客户端运算出来的结果必须⼀致。但是由于浮点数的特性，具有误差，且在不同设备上误差更为明显。因此所有...
numbers can be either fixed-point integers or fixed-point decimals, depending on the position of the decimal point.Unlike floating-point numbers, the decimal point position of fixed-point numbers is fixed, limiting their numerical range and decimal precision. In modern computers, fixed-point ...
