strtoimax method
Converts the string nptr to an intmax_t.
Trims leading whitespace, handles optional signs, stops at the first invalid
character, and autodetects the radix (base) if radix is 0 (e.g. 0x for 16).
Implementation
intmax_t strtoimax(String nptr, {int radix = 10}) {
return _parseWithCStyle(nptr, radix);
}
