How to format number in PostgreSQL?

@tressie.damore 

In PostgreSQL, you can use the to_char function to format a numeric value as a string. For example:

1

SELECT to_char(12345.678, '9999.99') as formatted_number;

This will return the string '12345.68'. The format string '9999.99' specifies that the number should be formatted with at least 4 digits before the decimal point and 2 digits after the decimal point.

You can use various formatting options to control the appearance of the formatted number. For example:

• FM: suppresses leading and trailing zeros
• $: adds a currency symbol
• 9: a digit placeholder
• 0: a zero placeholder
• .: the decimal point
• ,: the thousand separator

Here are some examples of how you can use these formatting options:

SELECT to_char(12345.678, 'FM$9,999.99') as formatted_number;
-- Returns '$12,345.68'

SELECT to_char(12345.678, '$9,999.00') as formatted_number;
-- Returns '$12,345.68'

SELECT to_char(12345.678, '$9,999.00') as formatted_number;
-- Returns '$12,345.68'

SELECT to_char(12345.678, '$9,999.00') as formatted_number;
-- Returns '$12,345.68'

SELECT to_char(12345.678, '$9,999.90') as formatted_number;
-- Returns '$12,345.68'

SELECT to_char(12345.678, '$9,999') as formatted_number;
-- Returns '$12,346'

SELECT to_char(12345.678, 'FM$9,999') as formatted_number;
-- Returns '$12,346'

SELECT to_char(12345.678, 'FM$9,999.90') as formatted_number;
-- Returns '$12,345.68'

I hope this helps! Let me know if you have any questions.

In PostgreSQL, you can format numbers using the to_char() function. This function accepts two arguments: the number to be formatted and a format string.

Here is an example of how to format a number in PostgreSQL:

1

SELECT to_char(1234.5678, '999,999.99');

This will output the number as "1,234.57".

In the format string, the "9" represents a digit and the "," represents a group separator. The "." is used to separate the integer and fractional parts of the number.

You can also include other characters in the format string, such as a currency symbol:

1

SELECT to_char(1234.5678, '€999,999.99');

This will output the number as "€1,234.57".

You can customize the format string to suit your specific formatting needs. The PostgreSQL documentation provides a complete list of format elements that you can use: https://www.postgresql.org/docs/current/functions-formatting.html
