Description

The PS Ceil block rounds the input physical signal toward positive infinity, that is, to the nearest integer larger than or equal to the input value:

O=ceil(I)

where

IPhysical signal at the input port
OPhysical signal at the output port

Both the input and the output are physical signals. Untyped physical ports facilitate the signal size propagation. However, arguments passed to rounding functions (such as ceil) must be dimensionless. Therefore, the input signal must have the unit of 1 (unitless), and the output signal is also unitless.

Input physical signal. Arguments passed to rounding functions (such as ceil) must be dimensionless. Therefore, the input signal does not have to be a scalar but must have the unit of 1 (unitless).

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Output
