from decimal to binary and viceversa 1249 0
Started by Deleted User
Hi everyone,
I am stuck with binary conversion..
I need to convert decimal number to binary and again to decimal. From coyote`s guide I found the code to convert from decimal to binary but I can`t return to decimal, expecially with floating values. The most common floating-point binary storage is not friendly to understand...Some suggestions
Thanks
Michele

Hi all,

more recent data includes the NOAA-19 version of the AVHRR sensor. IDL fails to process imagery from this particular sensor as it does not recognise the AVHRR satellite ID.

IDL Bridge - ELFCLASS64 error 968 0

I'm trying to deploy a Java Webapp that uses the Java-IDL Bridge onto a local test glassfish environement. Previously, we had it working on another server, but we were trying to upgrade to a better machine.
