[英]Rounding float numbers TypeError: 'float' object cannot be interpreted as an integer
为什么不起作用,我收到错误:TypeError: 'float' object 不能被解释为 integer
我的代码
qtyprice = 0.5221932114882507
lot_size = 0.1
quantity = float(round(qtyprice, lot_size))
print (quantity)
我的预期结果应该是 0.5
当我尝试这种方式时,结果为 0
qtyprice = 0.5221932114882507
lot_size = 0.1
qtyprice = int(qtyprice)
lot_size = int(lot_size)
quantity = float(round(qtyprice, lot_size))
print (quantity)
round 的第二个参数是round
后要“保留”的小数点后的位数,这个数字应该是一个 int,在你的情况下应该是 1
这应该可以解决问题:
qtyprice = 0.5221932114882507
lot_size = 1 #what i changed
quantity = float(round(qtyprice, lot_size))
print (quantity)
output:
0.5
