FAQ
What's the difference between DEG and RAD?
In DEG (degrees), a full circle is 360° — common in school math. In RAD (radians), a full circle is 2π — used in higher math/physics. The default is DEG.
How do I use memory (M+, MR, MC)?
M+ adds the current result to memory, MR recalls the value from memory, MC clears memory — for saving intermediate results in long calculations.
Does it handle scientific notation?
Yes — very large or small numbers automatically display in scientific notation (e.g. 1.5e+10).
