Scientific Notation Calculator

Scientific notation: M × 10^n where 1 ≤ |M| < 10 (M can be negative; zero is shown as 0.0000e+0). Examples: 6,200,000 = 6.2×10^6; 0.000045 = 4.5×10^-5. The scientific form is shown to 5 significant digits (4 decimals in the coefficient) and the standard form to 8, so long inputs are rounded. Number B is used only for the operations.
