Integers include the positive and negative whole numbers including zero. An integer cannot be a decimal or fractional part with it.

The set of integers is denoted by the numbers $\mathrm{...},−4,\text{ }−3,\text{ }−2,\text{ }−1,\text{ }0,\text{ }1,\text{ }2,\text{ }3,\text{ }4,\text{ }\mathrm{...}$

On a number line, a number is greater than every number to its left and less than every number to its right. In other words, when moving on the number line from the left-most number to the right-most number of a given set of numbers, the numbers are encountered in the increasing order of their value.

Observe that the given numbers have the same whole part as 0, but the decimal part of the first number 0.32 is greater than the decimal part of the second number 0.23.

And both the numbers are positive, so 0.32 must be on the right side of 0.23 on the number line, that is, 0.32 must be greater than 0.23.

Thus, the correct statement is $0.32\text{ }>\text{ }0.23$.
