Convert an integer from decimal to hexadecimal.

Uses Lua:

Usage

If the input is an empty string, the result is an empty string.
Non-integer and negative values are truncated to unsigned 64-bit integers (with a maximum of 16 hexadecimal digits returned).
The returned hexadecimal digits A to F are in upper case.
However the precision is limited to the most significant 44 bits (11 hexadecimal digits), and less significant digits are rounded when converted back to decimal; the inverse conversion from hexadecimal to decimal is warrantied to be a distinct positive integer string only within this limited range; values in larger ranges will result in an decimal floating-point string, possibly negative and with a limited precision in terms of significant digits.
For example:
- {{DecHex|17592186044414}} returns FFFFFFFFFFE and {{HexDec|{{DecHex|17592186044414}}}} returns 17592186044414
- {{DecHex|17592186044415}} returns FFFFFFFFFFF and {{HexDec|{{DecHex|17592186044415}}}} returns 17592186044415
But higher integer values are rounded when converted back to decimal from hexadecimal, even if the hexadecimal string is correct in the positive 64-bit range:
- {{DecHex|17592186044416}} returns 100000000000 and {{HexDec|{{DecHex|17592186044416}}}} returns 17592186044415
- {{DecHex|140737488355327}} returns 7FFFFFFFFFFF and {{HexDec|{{DecHex|140737488355327}}}} returns 1.4073748835533e+14

Parameter	Description		Default	Status
`1`	a decimal integer to convert		empty	optional
`2`	the minimum count (1 to 16) of hexadecimal digits to return (left-padded with zeroes when needed)		1	optional
