Can I give an example of a rounding error in floating-point arithmetic? Sure, let's say you have two floating-point numbers, 0.1 and 0.2, and you add them together. In decimal arithmetic, the sum would be 0.3. However, due to rounding errors in floating-point arithmetic, the result mig...
Simply stated, floating-point arithmetic is arithmetic performed on floating-point representations by any number of automated devices. Traditionally, this definition is phrased so as to apply only to arithmetic performed on floating-point representations

如果用四舍五入就没问题了 为什么有了保护位,精度反而下降了? 保护位保护的是652.0和7.4765625这里面的数字,而未必是原来数字的精度

浮点数就是小数点位置不固定的数,也就是说与定点数不一样,浮点数的小数点后的小数位数可以是任意的,根据IEEE754-1985(也叫IEEE Standard for Binary Floating-Point Arithmetic)的定义,浮点数的类型有两种:单精度类型(用4字节存储)和双精度类型(用8字节存储)。
An important open problem is to design fast SMT solvers for floating-point arithmetic =-=[42]-=-. Weak memory models. Analysis tools for concurrent programs need to consider the problem of weak memory models exhibited by all modern multicore architectures (e.g., x86 or Power), where the ...
The IEEE standard for arithmetic specifies a way of handling underflowed results gradually by dynamically adjusting the radix point of the significand. In IEEE floating-point format, the radix point occurs before the significand, and there is an implicit leading bit of 1. Gradual underflow allows ...
2. Fixed-precision floating-point arithmetic A b-bit floating-point number is a real number of the form 2 e f where e and f are integers with |f| < 2 b . Theorem 2.1. Let b be a nonnegative integer, and let k be an integer. Let x be a ...
of graphics.It's important to note that floating-point arithmetic can introduce rounding errors because computers can only store and compute floating-point numbers with finite precision. While this error is tolerable in most applications, special care must be taken when high precision is required.
