Usage<br />

Mathematical Function<br />

ceil(VAL)<br />

Waveform Function<br />

ceil(wf)<br />

ceil(wf, x_start, x_end)<br />

Arguments<br />

Mathematical Function<br />

• VAL<br />

Value.<br />

Waveform Function<br />

• wf<br />

Waveform identifier.<br />

• x_start<br />

Waveform start point.<br />

• x_end<br />

Waveform end point.<br />

Return Values<br />

Mathematical Function<br />

Returns the smallest integer value not less than VAL. This is known as rounding up. For<br />

example ceil(1.25) returns 2.0 and ceil(-1.25) returns -1.0.<br />

Waveform Function<br />

Computes the smallest integral value not less than each data point of a waveform wf (the result<br />

is a waveform).<br />
