The structure of my byvector is: 30.0(float) --- IEE754 converter --> 0x41F00000 (hexadecimal) --- little endian ---> 0000F041 --- hexadecimal to decimal converter ---> 00 00 240 65
But I didn't notice and there's a lot of zeros before the next 00 00 240 65. I have to study what is the structure of a f32vector in Guile. I don't know it. I also have to see what you said about #:stride 3 . Thanks.
