Math::Round -- Perl extension for rounding numbers Math::Round is a Perl module. It supplies functions to round numbers, both positive and negative, in various ways. This may seem like an odd thing to write a whole module for, but rounding can sometimes be a little tricky, so I thought some people might find this useful. round: round to the nearest integer; numbers ending in .5 go "to infinity" (3.5 becomes 4, -3.5 becomes -4) round_even: round; numbers ending in .5 go to the even number round_odd: round; numbers ending in .5 go to the odd number round_rand: round; numbers ending in .5 go up or down randomly nearest: round to the nearest multiple of any number nearest_ceil: like nearest; numbers halfway between two multiples go up nearest_floor: like nearest; numbers halfway between two multiples go down nearest_rand: like nearest; numbers halfway between two multiples go up or down randomly nlowmult: next lower multiple of a number nhimult: next higher multiple of a number Recent Changes ============== Version 0.04: Added nearest_ceil and nearest_floor. Version 0.05: Added nlowmult and nhimult. Version 0.06: Streamlined the code. How to Install ============== perl Makefile.PL make make test make install Copyright © 2002 Geoffrey Rommel.
