Function Reference

Hex

Returns a string representation of an integer converted to hexadecimal.

Hex ( number, length )

Parameters

number	The integer to convert.
length	Number of characters to be returned (up to 8). Characters are truncated from the left-hand side if length is too small.

Return Value

Success:	Returns a string of length characters, zero-padded if necessary.
Special:	Returns null string if length is less than 1.
Failure:	Returns null string and sets @error to 1 if length is greater than 8.

Remarks

The function only works with numbers that fit in a 32 bit signed integer (-2147483648 to 2147483647)

The function will also set @error to 1 if not enough digits were requested - the returned string will return the least significant digits in this case.
