# BinStr

Convert integer to string with binary representation.

## Declaration

Source position: systemh.inc line 1186

`function BinStr(`
`Val: LongInt;`
`cnt: Byte`
`):shortstring; function BinStr(`
`Val: Int64;`
`cnt: Byte`
`):shortstring; function BinStr(`
`Val: QWord;`
`cnt: Byte`
`):shortstring;`

## Description

BinStr returns a string with the binary representation of Value. The string has at most cnt characters. (i.e. only the cnt rightmost bits are taken into account) To have a complete representation of any longint-type value, 32 bits are needed, i.e. cnt=32

## Errors

None.
