Safe conversion from FString to float?

The isNumeric function is like this in the engine:

	static bool IsNumeric(const CharType* Str)
	{
		if (*Str == '-' || *Str == '+')
		{
			Str++;
		}

		bool bHasDot = false;
		while (*Str != '\0')
		{
			if (*Str == '.')
			{
				if (bHasDot)
				{
					return false;
				}
				bHasDot = true;
			}
			else if (!FChar::IsDigit(*Str))
			{
				return false;
			}
			
			++Str;
		}

		return true;
	}

“12.12” should still be considered as numeric as long as there is only one decimal point.
