FAQ

What can I type?

Use plain decimals, grouped numbers such as 12,345.6, e notation such as 1.23e4, or ×10^n notation such as 1.23 × 10^4. Superscript powers like ×10⁴ work too.

How is engineering notation different?

Engineering notation keeps the exponent as a multiple of 3. That makes values line up with SI prefixes such as kilo, mega, micro and nano.

Does it round the number?

No. The result is made from the digits you enter, not from a floating-point approximation. Redundant leading and trailing zeros are cleaned up.
