Frequently Asked Questions
1. I want to do an XOR operation with two binary numbers. I change to binary display and enter 11101^1110, but the answer is huge. What’s wrong?
The proper notation should be: 0b11101@0b1110. First, the display base is binary, but the default base when entering numbers is always decimal. A number must start with 0b to indicate binary representation. Second, in CCalc the ^ symbol is not the XOR operator, ^ is the power or exponent operator. Please see the CCalc Operators List in the manual.
2. Is there an IF function like Excel: IF(x==3, 4, 5) ?
Meaning, if x==3, then 4, else 5. No, it is not built-in, but you can define such a function yourself. Here is an example:
IF(tf,a,b) = (tf!=0)*a+(tf==0)*b
3. Why does the minus key ‘-’ not operate on the previous answer like +, * and / ?
At the start of a new prompt, most operator keys automatically insert ‘ans’ to operate on the previous answer, but ‘-’ is sometimes intended to enter a negative number, not subtract something from the previous answer. If you want to operate on the previous answer, just press the minus key twice, and ‘ans-’ will appear.
4. I purchased a license for CCalc (Windows version). When will I get a registration code, and how do I enter it?
You will receive an email with the registration code and instructions to register. You will receive an email within 24 hours, but the process is only semi-automated, so plus or minus a few hours. When you get your registration code email, type “register ccalc” at the prompt, or go to the “Help” menu, “About CCalc”, and “Enter Reg Code”.
5. Is there a CCalc variant for Linux?
Nope. I’ve had success running CCalc using WINE, however.
6. What about CCalc for the iPhone?
Unlikely. The console + keyboard interface makes CCalc great for a PC, but doesn’t translate so well to an iPhone.
