NAME

math -- performs simple math operations

MATH - OSIRIS library of scripts

DESCRIPTION

math is a wrapper for "echo ... | bc -lm"

EXAMPLES

math 2 + 3 will do addition
math "2 * 3" does multiplication (note the quotes when "*" used).
math 2 \* 3 another way of doing multiplication without quotes.
math 2 x 3 is also multiplication (no quotes needed)
math 4 - 5 subtraction
math 4 / 5 division.

For use within scripts, with passed arguments:
mxy `math $x x $offset` `math $y x $offset`

(Note that the variable substitution for $x happens before the "x"
representing multiplication gets translated into "*".)
