 If s is too big or too small to fit into a fixed-point number, returns [[constants:INT_MAX]] with the sign of the input.

+Supports signs and [[:Number prefixes]].
 <note important>This function parses the fractional part only up to the amount of digits that can be stored in a fixed-point number. This means that numbers with very long fractional parts will not be fully parsed, e.g. ''%%"0.12345678901234567890thisisnotanumberanymore!@#$^#$^$*%^*$"%%'' will parse successfully.

+<note tip>For more flexibility in parsing and error handling, use [[ParseFixed]].</note>
