sign 计算各元素的正负号:1(正数)、0(零)、-1(负数)。 ceil 计算各元素的ceiling值,即大于等于该值的最小整数。 floor 计算各元素的floor值,即小于等于该值的最小整数。 rint 将各元素值四舍五入到最接近的整数,保留dtype。 modf 将数组的小数部分与整数部分以两个独立数组的形式返还。 isnan 返回一个表...
Python math module providesceil()andfloor()functions to rounded up and rounded down the any value. The floor and ceiling functions generally map a real number to the largest previous or smallest following integer which has zero decimal places. So to use them for 2 decimal places the number is...

ROUND_CEILING (towards Infinity), ROUND_DOWN (towards zero), ROUND_FLOOR (towards -Infinity), ROUND_HALF_DOWN (最接近零的关系), ROUND_HALF_EVEN (到连接最近的偶数到最近的连接), ROUND_HALF_UP (距离零距离的关系最近), ROUND_UP (远离零)。 ROUND_05UP (如果在舍入到零后的最后一位数字将为...
In this case, calling int() is equivalent to calling math.trunc(), which rounds positive fractions down and negative fractions up. These two operations are known as floor and ceiling, respectively. You can use both directly if you want to:...
