3.8.26. RANDOM
Interface to the REXX pseudorandom number generator. Returns a pseudorandom
integer from <min_expression>> to <max_expression>, inclusive, and optionally re-seeds the
generator with <seed_expression>, evaluated and rounded to an integer. Default values :
<min_expression ≥ 0, <max_expression ≥ 100,000. One restriction is that the difference
between the maximum and minimum limits must not exceed 100,000.
Syntax: Random(<min_expression>, <max_expression>, <seed_expression>)
3.8.27. ROOT1D
Finds a root of the given expression. Guess1 and guess2 must have opposite signs.
Currently just a stub.
Syntax: Root1D(expression, unknown, guess1 guess2, min max)
3.8.28. ROUND
Rounds expression to the specified number of decimal places, or to the nearest integer.
Numbers exactly halfway between steps are rounded up.
Syntax: Round(<expression>[, <places>])
3.8.29. SIGN
Signum function. Returns +1, 0, -1 for <expression> >0, =0, and <0.
Syntax: Sign(<expression>)
3.8.30. SIN
Returns the sine of radian angle <expression>.
Syntax: sin(<expression>)
3.8.31. SQRT
Returns the square root of a non-negative number.
Syntax: Sqrt(<expression>)
3.8.32. TAN
Returns the tangent of radian angle <expression>.
Syntax: tan(<expression>)
3.8.33. TRUNC
Evaluate <expression> and truncate (round towards zero).
Syntax: trunc(<expression>)
