idea开发的时候,Math.ceil(Integer.parseInt(num)/1000)发现有黄线,出现了‘integer division in floating-point context’提示。 写一个main方法发现Math.ceil(4800/1000)结果居然是4.0,查了一下:两个整数相除,结果必定是整数。如果用float、double等数据类型接收,语法上不构成错误,但是会丢失精度。 解决方法很简单,...

One embodiment of the present invention sets forth a technique for performing fast integer division using commonly available arithmetic operations. The technique may be implemented in a four-stage process using a single-precision floating point reciprocal in conjunction with integer addition and ...

请注意,from __future__ import division必须放在文件的开头。- yannis 显示剩余2条评论 752 您可以通过执行c = a / float(b)来将其转换为浮点数。如果分子或分母是浮点数,则结果也将是浮点数。 注意:正如评论者指出的那样,如果b可能不是整数或浮点数(或表示其中之一的字符串),则此方法将无法正常工作。如果...
In the first case, we cast the numerator to a float. This guarantees that the division operation considers floating-point arithmetic, resulting in a more accurate output. Similarly, in the second case, we cast the denominator to a float. Once again, this ensures that the division involves at...
