| Keyword | Abbreviation | Token (hex) | Version(s) | Classification |
| HEX$ | H{Shift+E} | D2 | 3.5, 7.0 | Function |

HEX$ ( number )
| Parameters | Type | Legal Value(s) | Default Value | Note(s) |
| number | Unsigned Integer | 0 to 65535 | | |
| Returns | Type | Value(s) | Note(s) |
| hexString | String | 4 characters | |
Return a string containing a hexadecimal represention of the give number.
The HEX$ function conceptually performs decimal to hexadecimal conversion.
As you probably know, the computer works with binary numbers in reality.
Anyway, the given number is used to generate a 4-character hexString.
Unlike the similar STR$ function, this one is a cry-baby; HEX$ has a very limited domain
and the result will often include leading zeros.
You will get TYPE MISMATCH ERROR with a string expression or variable given
for the number (the VAL function may help). A floating-point number
will be converted to an integer (see INT). An ILLEGAL QUANTITY ERROR is generated
if the number is not a Legal Value (see table above).
Examples:
PRINT HEX$("65")
?TYPE MISMATCH ERROR
READY.
PRINT HEX$(65)
0041
READY.
PRINT HEX$(65.6)
0041
READY.
PRINT HEX$(-65.6)
?ILLEGAL QUANTITY ERROR
READY.
PRINT HEX$(65E6)
?ILLEGAL QUANTITY ERROR
READY.
