Byte format of "single" data type

Can anyone explain the byte format (4 bytes) of the Delphi "single" floating point data type.
I have a Delphi app that writes "single" data type values to a file and I would like to read the data file using a non-Delphi app.

It's the normal IEEE standard single data type.

Hi zebada,

It's really standard type. E.g. it used in 80287 coprocessor.
31 bit - Sign
30...23 Exponent
22...0 Fracation

If you are going to load it to application that  builded with compiller supported "Single type", then just load it directly to variable.

Thanks to all,

AvonWyss was first. I should've known but I was using "Hex Editor" with the byte order accidentally set to Motorola instead of Intel. So I was seeing really strange numbers when it was interpreting the 4-byte single values. I concluded (incorrectly) that Delphi was using non-standard floating point formats. DOH!

Cheers
