real(int) round(real _arg, real _decimals); 利用INT函数构造四舍五入的函数返回的结果精度有限,有时候满足不了我们的实际需要。Excel的Round函数可以解决这个问题。一、ROUND函数中:1、如果 num_digits 大于 0(零),则将数字四舍五入到指定的小数位。 如果是A=6.66,round(A, 1.1到1.9) round函数在hive...
python -c "print(round(number, 2))" python -c allows running a Python command as a string from the shell. print(round(number, 2)) calls Python’s round function, rounding the number to two decimal places. The number in the Python command is the shell variable and needs to be passed...

JAVA float double数据类型保留2位小数点5种方法 2015-08-28 10:51 −/** * Java 两个整数相除保留两位小数,将小数转化为百分数 * java中,当两个整数相除时,由于小数点以后的数字会被截断,运算结果将为整数,此时若希望得到运算结果为浮点数,必须将两整数其一或是两者都强制转换为浮点数。 例如: (float)a...
Unicode与Ascii区别:Unicode编码表包含ASCII的所有内容,同时还包括了全世界的语言,ASCII只有1字节,而Unicode编码是2字节,能够代表65536种文字,足以包含全世界的文字了!(我们编译出来的字节码文件也是使用Unicode编码的,所以利用这种特性,其实Java支持中文变量名称、方法名称甚至是类名) ...
