hey /sci/,

if i want to say a number with decimal fraction is odd or even, do i evaluate based on the proximity to the decimal?

example: 123.45 would be decimal fraction even, because of the 4.

pic related, it's me calculating the number of this post

 >> Anonymous Mon Jun 4 01:58:27 2018 No.9787856 Odd and Even are descriptions exclusive to the integers. Odd means that the integer can be expressed as 2(some integer)-1, and Even means that the integer can be expressed as 2(some integer). You could try to extend the definition to suit your purposes but I don't see the point.

 >> Anonymous Mon Jun 4 03:30:58 2018 No.9787927 >>9787915Okay. A rational number p/q is said to be even if the integer p is even, and odd if p is odd. That's my definition. No standard one exists.
