OK, seems like there’s interest in some quick calc tips. Here’s today’s:

How to convert decimal to hexidecimal. Let’s say you want to convert number 12345 to hex.

M-x calc
d 6 (sets the number radix to 16, meaning all output will be in hex)
10#12345 (inputs the number 12345 in base 10)

The output reads:
1:  16#3039

The answer is therefore 0x3039.

And then you can do a d 0 to set the number radix back to normal, base 10.

Here’s how to do the other way. Let’s convert 0xABCDEF to base 10.

M-x calc
16#ABCDEF

The output reads:
1:  11259375
