StreamDevice for an odd float format

["Brown, Garth via Tech-talk" <tech-talk@aps.anl.gov>]

Hi All,

I'm trying to use StreamDevice to talk to a device that is almost, but not quite, giving me data that the format converters (as I understand them) can convert.

It’s an ASCII representation of the IEEE 32 bit floating point format, e.g. the raw data for a value of 28.0 is

0x34 0x31 0x45 0x30 0x30 0x30 0x30 0x30

Which is the ASCII code for

41E00000

Which is the IEEE-754 floating point representation of 28.0.

I think that if the raw data were 0x41E00000, %R would be able to convert it. And if the raw data were

0x32 0x38 0x2E 0x30 (ASCII for 28.0)

then %f would be able to convert it.

Before I start writing calc records to convert the 32 bits to a float value, I figured I'd ask if someone had a less brute-force approach. Maybe a StreamDevice format converter trick I don't know about?

Thanks,

Garth
