## digitalmars.D.learn - "float" on 3 bytes

- tsalm (11/11) Oct 09 2008 Hi,
- Denis Koroskin (3/14) Oct 10 2008 There are 24- and 16-bit floating point type libraries available in C
- tsalm (1/18) Oct 10 2008 Interesting. Thanks

Hi, I need to minimize the size of my memory use... My program uses a big array of float. My float have a gap of 0.0000001 and 65536. So i think to store one sort of "float" with : - an "ushort" to have numbers - and a "ubyte" to have the number of digit in the decimal portion (or something like this...). What could be the better way for you ? Thanks in advance for your help, TSalm

Thanks in advance for your help, TSalmThere are 24- and 16-bit floating point type libraries available in C (google for half-float), these could be easily ported to D.
