金币num的表现形式（t s）

例如：900000000 返回的表现形式为：900，000，000

public static formateNum(num,addName?:string){

let prename = '';

if(addName)prename = addName;

if(num > 1000){

let tempNum = num;

let newPath = '';

while(tempNum > 1000){

let tempPath = '';

if(tempNum%1000 == 0){

tempPath = ',000';

}else{

if(tempNum%1000 < 10){

tempPath = ',00'+ tempNum%1000;

}else if(tempNum%1000 >= 10 && tempNum%1000 < 100){

tempPath = ',0'+ tempNum%1000;

}else{

tempPath = ','+ tempNum%1000;

}

}

newPath = tempPath + newPath;

tempNum = Math.floor(tempNum/1000);

}

newPath = prename + tempNum + newPath;

return newPath;

}else{

return prename+num;

}

}
