Post by thread:[OT] Floating point formats

Hello all, I have a problem which doesn't belong here but I'm still turning to the piclist 'cause I know I can find a lot of skilled ppl here, who maybe can solve my problem. I'm working on an 186 AMD based micro. This this is programmed in Borland C++ 5. The problem I have is with floating points. As this this doesn't have a fp processor onboard, I'm using Borlands fp emulation library (emu.lib). What I am trying to do is send a 32 bit float value over a certain connection, byte for byte. However, If I put them all together again on the other side and hope to get the same float back, I am mistaken. Therefore, I came to the conclusion the emu.lib uses a non standard (i.e. IEEE754), fp format. And I am at a loss which one that should be. Extensive googling only gave me a bunch of unreadable pages and highly arcane info. Any ideas for this one?

Convert to/from a string using scientific notation and send as a string.
