Re: How to Define High-precision Date type

The precision of built-in date type of C is very low. Even using long
double float type or double float type, we can only use 12 or 16
digits after the decimal point. What can we do if we want to use
high-precision number such as the number with 50 digits after the
decimal point. Can we define a user date type?
