# HexStr

Convert integer value to string with hexadecimal representation.

## Declaration

Source position: systemh.inc line 1184

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

`):shortstring; function HexStr(`
`Val: QWord;`
`cnt: Byte`
`):shortstring; function HexStr(`
`Val: Pointer`
`):shortstring;`

## Description

HexStr returns a string with the hexadecimal representation of Value. The string has exactly cnt characters. (i.e. only the cnt rightmost nibbles are taken into account) To have a complete representation of a Longint-type value, 8 nibbles are needed, i.e. cnt=8.

## Errors

None.
