Frequently Asked Questions
What is the difference between DEG and RAD?
DEG means degrees and RAD means radians.
Most everyday angle calculations use degrees. Higher-level mathematics and some engineering calculations may use radians.
Can I use my keyboard?
Yes. You can use your keyboard for numbers, decimal points and standard arithmetic operators.
You can also use the on-screen calculator buttons.
How do I use the memory buttons?
M+ adds the current value to memory.
M− subtracts the current value from memory.
MR recalls the stored value and MC clears it.
Why are some results rounded?
Some mathematical calculations produce a very large number of decimal places.
The calculator may round the displayed value to keep the result readable.
What does Ans do?
Ans inserts the answer from your previous calculation into the current calculation.
25 × 4 = 100
Next calculation:
Ans ÷ 5 = 20
Does the calculator work on mobile phones?
Yes. The Scientific Calculator is designed to work on desktop computers, laptops, tablets and mobile phones.
What does EXP mean?
EXP is used when entering numbers in scientific notation.
1.5 EXP 6
Are the results guaranteed?
No. The calculator is provided as a general calculation tool.
Important professional, engineering, scientific, financial, medical or safety-critical calculations should always be independently verified.
Please Note
The CS17 Scientific Calculator is provided for general use. For professional, scientific, engineering or safety-critical work, independently verify important calculations before relying on the result.
