x = a × 10ⁿ, with 1 ≤ |a| < 10 for x≠0

Variables & units

Finite number
Numeric value · minimum -1e+100, maximum 1e+100
Significant figures
Numeric value · minimum 1, maximum 15

Worked example

123456 to 6 significant figures is 1.23456e+5.

Assumptions

Exponential notation uses e for powers of ten, not Euler’s constant. The source number is stored as a JavaScript floating-point value.

Formula version 1.0.0. JavaScript floating-point arithmetic applies. Results display up to 6 decimal places; stored values retain available precision. Use the units shown.
