If the input string is supposed to represent a decimal number, and if it has
leading 0’s, then those 0’s will have to be removed before passing the string
to the int function, else that string will be tried to be parsed as an octal
number representation.
The
strings.TrimLeft function
can be used for
this purpose.
{{ int ("0987" | strings.TrimLeft "0") }}
{{ int ("00987" | strings.TrimLeft "0") }}
Explanation
The int function eventually calls the ParseInt function from the Go library
strconv.
From its
documentation
:
the base is implied by the string’s prefix: base 16 for “0x”, base 8 for “0”,
and base 10 otherwise.
