Function ruby_strtod 

pub unsafe extern "C" fn ruby_strtod(
    str_: *const c_char,
    endptr: *mut *mut c_char,
) -> f64

Our own locale-insensitive version of strtod(3). The conversion is done as if the current locale is set to the “C” locale, no matter actual runtime locale settings.

@param[in] str Decimal or hexadecimal representation of a floating point number. @param[out] endptr NULL, or an arbitrary pointer (overwritten on return). @return Converted number. @post If endptr is not NULL, it is updated to point the first such byte where conversion failed. @note This function sets errno on failure. - ERANGE: Converted integer is out of range of double. @see William D. Clinger, “How to Read Floating Point Numbers Accurately” in Proc. ACM SIGPLAN ’90, pp. 92-101. https://doi.org/10.1145/93542.93557
