Harbour and floats

[dissonantdev]

Hello! I'm new here so I hope you guys can lend me a hand if at all possible.

First I should disclose that I know pretty much nothing about Harbour, however I recently became interested in learning about it; so my question might already have an obvious answer!

For those of you that know, how does Harbour represent floats? Does it have any kind of limited-precision or arbitrary-precision decimal type?
I need something either like the limited precision decimal type in C# or something with arbitrary precision like Java's BigDecimal.

I personally use gmplib in C++, can that be used with Harbour?
GMP is a C library, and I think I heard in passing that Harbour can import and use C stuff; anyone that knows?

And last question! I recently found (10 minutes ago) Alexander Kresin's Harbour manual, but I thought I'd ask anyway.
Are there any other recommended resources to learn a bit more about the language?

Thank you for your time!

In hbapi.h:
#define HB_IT_DOUBLE 0x00010

Code: Select all | Expand

struct hb_struDouble
{
   double value;
   HB_USHORT length;
   HB_USHORT decimal;
};

Search for double in hbapi.h and review all related doubles functions
You may also review hbfloat.h

2) You can use any C library from Harbour:
