Scientific Notation Converter
Convert a number into mantissa × 10ⁿ form.
How it works
value = a × 10ⁿ with 1 ≤ |a| < 10
E.g. 12345 = 1.2345 × 10⁴. Useful for very large or very small numbers.
Worked example
0.00042 = 4.2 × 10⁻⁴; 5,600,000 = 5.6 × 10⁶.
Multiply: (2×10³) × (3×10⁻⁵) = 6×10⁻².
Notes and limitations
Normalised form requires 1 ≤ |a| < 10. For addition, align exponents first; for multiplication, handle coefficients and exponents separately. Do not lose significant figures when rewriting.
