There are many situations where you have to format variables on the template side.
I want to make image management in three digits, such as 001,002, or file name.
Do you want the score display to show max's number of digits?
I would like to introduce the variable modifiers that can be used on the Smarty template side.
string_format — Changing variable numbers
Suppose the contents of a variable called $num were 2.4362.
{$num}
{$num|string_format: "%.2f"}
{$num|string_format:"%03d"}
{$num|string_format:"%02d"}
{$num|string_format:"%d"}
Actual view
2.4362 2.43 002 02 2
I think that the usage which puts 0 on the head is considerably used.The rest is when you make it an integer.
This is useful, for example, when you want to calculate a number and make it an integer.
The %.2f or the back is a type specifier.

Shape the date or time.smarty.now is a reserved variable that represents the current time. These are displayed as follows. The display format is specified in the "%H:%M:%S" part. There are a lot of variable modifiers, so I'll introduce only useful things. Smarty had only old books, but the following are recommended for getting started.
% - percent character.No arguments are required.
b - Treats the argument as an integer and represents it as a two-decimal line.
c - Treats the argument as an integer and represents it as a character of its ASCII value.
d - Treats the argument as an integer and represents it as a decimal number.
e - Treat arguments as scientific notation (e.g. 1.2e+2). Precision specifiers represent the number of decimal places in PHP 5.2.1 and later. Earlier versions meant the number of digits (one smaller value) of the significant number.
Same as E - %e, but use uppercase letters (for example, 1.2E+2).
f - Treats the argument as a double and represents it as a floating-point number.
F - Treats the argument as float and represents it as a floating-point number (locale-independent). Available in PHP 4.3.10 and PHP 5.0.3 and later.
g - %e and %f abbreviations.
G - %E and %f abbreviations.
o - Treats the argument as an integer and represents it as an 8-decimal number.
s - Treats the argument as a string and represents it.
u - Treats the argument as an integer and represents it as an unsigned 10-decimal number.
x - Treats the argument as an integer and represents it as a 16-decimal (in lowercase).
X - Treats the argument as an integer and represents it as a 16-decimal (in uppercase).
