If the format expression contains only characters to the left of this symbol numbers smaller than 1 begin with a decimal separator To display a leading zero displayed with fractional numbers use zero as the first digit placeholder to the left of the decimal separator In some locales a comma is used as the decimal separator The actual character used as a decimal placeholder in the formatted output depends on the number format recognized by your system Thus you should use the period as the decimal placeholder in your formats even if you are in a locale that uses a comma as a decimal placeholder The formatted string will appear in the format correct for the locale Thousand separator The thousand separator separates thousands from hundreds within a number that has four or more places to the left of the decimal separator Standard use of the thousand separator is specified if the format contains a thousand separator surrounded by digit placeholders 0 or A thousand separator immediately to the left of the decimal separator whether or not a decimal is specified or as the rightmost character in the string means scale the number by dividing it by 1 000 rounding as needed Numbers smaller than 1 000 but greater or equal to 500 are displayed as 1 and numbers smaller than 500 are displayed as O 6 Two adjacent thousand separators in this position scale by a factor of 1 million and an additional factor of 1 000 for each additional separato
