[C++] Hex And Binary

[Clyde]

Anybody know what the Hex and Binary symbols are please?

In FreeBASIC they are &H for Hex, and &B for Binary.
In Blitz they are the same symbol of $.

Thanks again,

@Clyde:

For Hex use 0x as prefix.
For bin I do not know. AFAIK there is no
explicit syntax - but maybe I am wrong

Benny is right, there is no explicit syntax for binary numbers, but clyde, you should be using hex anyway

thanks for the info

Yep, 0x prefix for hex, but no binary, you can do macros like:

Code Select Expand


#define BIN(a,b,c,d,e,f,g,h) (((a)<<7)|((b)<<6)|((c)<<5)|((d)<<4)|((e)<<3)|((f)<<2)|((g)<<1)|(h))

BIN(1,0,1,0,1,1,1,1)

will then work.

Interestingly C and C++ support octal as well using 0 prefix.  So 010 is actually 8 in decimal.
