Rounds the input to the next lowest integer.
For example, if the input is 3.8, the result is 3. If the input is -3.8, the result is -4.
An input to this operation.
This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.
The resulting lowest integer, closest to the input value.
When x is of the form x = a + bi, that is, when x is complex, the function returns a complex number defined by the next lowest integers to the real and imaginary parts of x. The following equation defines rounded number:
floor(x) = floor(a) + i floor(b)
