Log and antilog Calculator

Logarithm (base 10) & Antilog Calculator

SaitechAI

Number (supports scientific notation)

Precision (digits)

Result will appear here.

Notes: log₁₀(x) is defined only for x > 0. Input like 6.02 × 10^23 or 6.02e23 is accepted.

Log value x (can be decimal or in a+b format)

Precision (sig. figs)

Result will appear here.

Tip: For x = a + m, antilog is 10^a × 10^m. Example: 2 + 0.3010 → 10^2 × 10^0.3010 ≈ 200.
