# getvar

Purpose
Get the decision variable associated to a pseudo boolean.
Synopsis
`function getvar(bv:boolvar):mpvar`
`function getvar(indic:logctr):mpvar`
Arguments

bv | A pseudo boolean decision variable
indic | A logical constraint representing an indicator

Return value
The decision variable associated to the given parameter.
Further information
1. Each pseudo boolean variable is associated to two decision variables of type mpvar. This function makes it possible to retrieve these variables: it can be applied to both the variable itself ( e.g. getvar(bv)) and its negation ( e.g. getvar(not bv)).
2. The function may also be applied to an indicator constraint: in this case it returns the variable associted to this indicator (see indicator).
