Parameters
Return Type
String
Example
string a = formatNumber(123456.789 ,"###,###.###"); //The pound sign (#) denotes a digit, the comma is a placeholder for the grouping separator, and the period is a placeholder for the decimal separator. print("a= " + a); string b = formatNumber(12345.67, "$###,###.###"); print("b= " + b); string c = formatNumber(123.78, "000000.000"); //The format specifies leading and trailing zeros, because the 0 character is used instead of the pound sign (#). print("c= " + c); string d = formatNumber(123456.789, "###.##"); // The number has three digits to the right of the decimal point, but the format has only two. The format method handles this by rounding up. print("d=" + d);
Prints:
a= 123,456.789
b = $12,345.67
c= 000123.780
d=123456.79
