Frequently Asked Questions
What is scientific notation?
Scientific notation expresses very large or small numbers using powers of ten. For example, 1,230,000 becomes 1.23 × 10⁶.
How do I enter a number in scientific notation?
You can use 'e' format (e.g., 1.23e+8), caret format (1.23 × 10^8), or superscript format (1.23 × 10⁸). All are supported.
What are significant digits?
Significant digits reflect the precision of a number. You can choose how many digits to show in the converted result.
What is Standard Scientific Notation?
A form like 6.02 × 10²³ where the base is between 1 and 10 and multiplied by 10 to a power.
What is Scientific E-Notation?
Uses 'e' to indicate powers of ten, such as 6.02e23. Common in calculators and code.
What is Engineering Notation?
Similar to scientific notation, but exponent is a multiple of 3, aligning with metric prefixes.
Why does the Real Number say "Out of range"?
Real number output is only shown if the exponent is within the displayable range (up to 10²⁰). Very large/small values may exceed this.
