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

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
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 ...

6.2IEEE Floating-Point Arithmetic IEEE arithmetic is a relatively new way of dealing with arithmetic operations that result in such problems as invalid operand, division by zero, overflow, underflow, or inexact result. The differences are in rounding, handling numbers near zero, and handling numbers...
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)。
