Function parse_human_number

src/numfmt.c:1211–1233

Parse a numeric value (with optional suffix) from a string. Returns a long double value, with input precision. If there's an error converting the string to value - exits with an error. If there are any trailing characters after the number (besides a valid suffix) - exits with an error. */
