   I'd like to suggest adding the following aritmetic functions to perl.

      min(LIST)	- numerically lowest of LIST
      max(LIST)	- numerically highest of LIST

Sounds good.

      round(EXPR[,precision])
		   - EXPR rounded to precision decimal
		     places (default integer precision)
      ceil(EXPR)	- ceiling value of EXPR
      floor(EXPR)	- floor value of EXPR (identical to 'int')

Firstly, 'floor' is not 'int', because floor(-0.5) is -1, while
int(-0.5) is 0.  (Perl's 'int' is not the same as Algol's -- it really
should be called 'trunc'.)

I would like to see the optional 'precision' argument added to 'round',
'ceil', and 'int' as well.  And don't forget that precision can be
negative.
