// Starboard does not provide string to floating point number conversion at
// higher or lower precision than a double. This works for floats since a double
// is guaranteed to be at least as precise as a float, however, we would lose
// precision on systems where a long double is more precise than a double.
// However, since a long double is only required to be as precise as a double,
// the loss of precision is acceptable.
