x—An array or scalar of any real data-type, usually float or double.

result—A scalar or array of the same dimensions as x, where result(i) is the smallest integer greater than or equal to x(i). result is of type long unless the Floatingpoint keyword has been set.

Floatingpoint—If this keyword is present and the input array is of type float or double, the output array is of the same type as the input.

PRINT, SMALL_INT( [-0.5, 0, 0.5] )

; PV-WAVE prints: 0   0   1

x = [-2.1, -1.9, 0, 1.9, 2.1]

PRINT, SMALL_INT(x)

; PV-WAVE prints: -2   -1   0   2   3
