let(1)								   User Commands							    let(1)

NAME

       let - shell built-in function to evaluate one or more arithmetic expressions

SYNOPSIS

   ksh
       let arg...

   ksh93
       let [expr...]

DESCRIPTION

   ksh
       Each arg is a separate arithmetic expression to be evaluated.

   ksh93
       let  evaluates  each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari-
       ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...))  syn-
       tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments.

EXIT STATUS

   ksh
       ksh returns the following exit values:

       0    The value of the last expression is non-zero.

       1    The value of the last expression is zero.

   ksh93
       ksh93 returns the following exit values:

       0     The last expr evaluates to a non-zero value.

       >0    The last expr evaluates to 0 or an error occurred.
