» 3*2
6
Statement

» 6
Detail
Type Safety
Because shells are historically untyped, you cannot always guarantee that a numeric-looking value isn't a string. To solve this problem, by default Murex assumes anything that looks like a number is a number when performing addition.
» str = "2"
» int = 3
» $str + $int
1
For occasions when type safety is more important than the convenience of silent data casting, you can disable the above behaviour via config
(read more):
» config set proc strict-types true
» $str + $int
Error in `expr` (0,1): cannot Add with string types
> Expression: $str + $int
> : ^
> Character : 1
> Symbol : Scalar
> Value : '$str'
