Random (function)

Returns a measure value between 0 and 1, non-inclusive. Since this function uses the current system time when run inside the

printer, it returns a true random value. On the computer, however, the function uses the current data page as its seed to

ensure the returned value is constant when you navigate from page to page on your document.

Syntax

random() measure value

Argument

None

Code Sample Example

This example displays 10 random numbers between 1 and 20.

Example

define(&x,integer,1)

for(&x,1,1,10)

show(inttostr(floattoint(random()*20)+1))

crlf()

endfor()

Ceil (function)

Returns the smallest integer greater than or equal to the specified measure value.

Syntax

ceil( value ) integer value

Argument

value

Measure value. The absolute value of the measure value must be less than the maximum value of an integer in PostScript

(2,147,483,647).

Code Sample Examples

These examples illustrate various applications of ceil().

ceil( -2.8 ) %Returns -2

ceil( 2.8 ) %Returns 3

ceil( -5.0 ) %Returns -5
