Delphi中,inttohex能够实现二进制到十六进制的签名nat源码分析转换吗?
不能,可以将十进制整数转为十六进制字符串。手写手写
function IntToHex(Value: Integer; Digits: Integer): string; overload;
function IntToHex(Value: Int; Digits: Integer): string; overload;
第一个参数为整数值,源码chagtp网站源码搭建第二个参数为转换后十六进制字符串长度,签名设计模式源码图解转换后字符串长度小于第二个参数,手写手写前面补'0',源码转换后字符串长度大于第二个参数,签名返回实际十六进制字符串。手写手写
把二进制换为十六进制可以自己做一个函数
function BitoHex(BiStr:string):string;//函数,源码2进制串化成进制串
var i,签名Detmp:integer;
s:real;
begin
s:=0;
for i:=1 to length(BiStr) do
if BiStr[i]='1' then
s:=s+Intpower(2,length(BiStr)-i);
Detmp:=trunc(s);
Bitohex:=IntToHex(Detmp,2);//2个长度,根据自己二进制长度需求调整。手写手写互动直播游戏源码
