# roundrdsrec(3)

adjusts a rectangle to lambda grid step

## NAME

roundrdsrec - adjusts a rectangle to lambda grid step

## SYNOPSYS

```
#include "rfmnnn.h"
 void roundrdsrec( Rectangle )
    rdsrec_list ∗Rectangle;
```

## PARAMETER

- *Rectangle*

  RDS rectangle to treat.

## DESCRIPTION

the *roundrdsrec* function adjusts (in lambda) to lower grid step for rectangle extremity which has coordinates (X,Y), adjusts to upper grid step for rectangle extremity which has coordinates (X+DX,Y+DY).

## RETURN VALUE

nothing

## ERRORS

none

## EXAMPLE

```
        #include "mphnnn.h"
        #include "mutnnn.h"
        #include "rdsnnn.h"

         } UserStruct;
        main()
          {

            Rectangle   =
               addrdsfigrec(RdsFigure, "seg", RDS_ALU1, 2.5, 3.5, 6, 7);
            viewrfmrec ( Rectangle );
            /∗ ∗/ roundrdsrec ( Rectangle );
            /∗ view rectangle after rounding ∗/
