cnVCL whether add the function to conversion floating number to hexadecimal string ？

[sxbug]

cnFloat could conversion from 12.5 to C.8. Can it be converted to IEEE754's 41 48 00 00. I think this function is used a lot. thank you！

You can use function DataToHex(InData: Pointer; ByteLength: Integer; UseUpperCase: Boolean = True): string; in CnNative.pas to directly convert the memory content of Float number to a hex string.

given

var A: Single; begin Caption := DataToHex(@A, SizeOf(A)); end;

I only found the function: #1#2#3#4 <---> '1234'. But I want a function:12.5 <---> '41 48 00 00'

Thanks

Could you use my code piece and check the result?

var A: Single; begin A := 12.5; Result := DataToHex(@A, SizeOf(A)); end;

In above: function DataToHex(InData: Pointer; ByteLength: Integer; UseUpperCase: Boolean = True): string; is in cnvcl\Source\Crypto\CnNative.pas

Thank you for your guidance。

I misunderstand at first. Now I also want to know which function could convert # $41 48 00 00 to 12.5 ， hex-->single。

Happy Chinese new year!

There's also a function HexToData in CnNative.pas

Note:

1. Space Chars in String should be removed before calling this function.
2. Notice the BigEndian/Little Endian byte order after conversion.

These compoments is very good, but there are a few documents。Thanks
