Function S2I

Returns an integer by parsing the string for a number.

For values too big or too small, returns max/min integer respectively. For an empty string or text that doesn't start with a number, returns 0.

Lua: For null raises an error.

Examples (Lua):

S2I("") == 0
S2I("-123") == -123
S2I("-99999999") == -2147483648
S2I("99999999") == 2147483647
S2I("123abc") == 123
S2I("abc123") == 0
S2I(nil) -- error
Copy

Note

This function only works for decimal strings. Hexadecimal or octal strings are not supported.

Note

The parser stops at the first non-number character [0-9.]. If the input string starts with some valid input but ends in invalid input this will return the conversion of the valid part: S2I("123asd") == 123.
