[英]Round a float UP to next odd integer
How can I round a fload up to the next odd integer? 我如何能圆一个FLOAD 到 下一个奇数。 I found how it can be done for even numbers here .
我发现在这里偶数可以做到这一点 。 So I tried something like:
所以我尝试了类似的东西:
import numpy as np
def round_up_to_odd(f):
return np.ceil(f / 2.) * 2 + 1
But of course this does not round it to the NEXT odd number: 但当然这不会将其舍入到NEXT奇数:
>>> odd(32.6)
35.0
Any suggestions? 有什么建议么?
You need to ceil
before dividing: 分开之前你需要
ceil
:
import numpy as np
def round_up_to_odd(f):
return np.ceil(f) // 2 * 2 + 1
What about: 关于什么:
def round_up_to_odd(f):
f = int(np.ceil(f))
return f + 1 if f % 2 == 0 else f
The idea is first to round up to an integer and then check if the integer is odd or even. 这个想法首先是舍入到一个整数,然后检查整数是奇数还是偶数。
