Distance Modulus Calculator
Convert between positive parsec distance and astronomical distance modulus.
Open toolSoftmax Calculator
Convert finite logits to softmax probabilities with a supplied positive temperature. Provide Input logits, Positive temperature to compute results directly in your browser. The maximum logit is subtracted before exponentiation for stability. Probability_i = exp((x_i−max)/temperature) divided by their sum. Underflow can produce zero probabilities for distant logits; the values are not calibrated confidence estimates. Numeric output uses up to 12 significant digits; floating-point rounding can occur.

Practical Worked Examples for Softmax Calculator
These concrete scenarios illustrate how the Softmax Calculator processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Input logits = 1,2,3)
Input logits = 1,2,3; Positive temperature = 1. Output: Softmax probabilities: 0.0900305731704, 0.244728471055, 0.665240955775; Probability sum: 1; Temperature: 1.
Comparison scenario (softmax calculator online)
Input logits = 1000,1000; Positive temperature = 2. Output: Softmax probabilities: 0.5, 0.5; Probability sum: 1; Temperature: 2.
Boundary & unit check (Softmax Calculator)
When solving for 'softmax calculator', verify that Input logits, Positive temperature use consistent units and stay within the documented scope: The maximum logit is subtracted before exponentiation for stability. Probability_i = exp((x_i−max)/temperature) divided by their sum. Underflow can produce zero probabilities for distant logits; the values are not calibrated confidence estimates. Numeric output uses up to 12 significant digits; floating-point rounding can occur.
How to Read and Verify the Softmax Calculator Output
The output panel reports the exact result derived from Input logits, Positive temperature alongside any unit or formatting notes.
Every calculation follows the rule: Convert finite logits to softmax probabilities with a supplied positive temperature. Because JavaScript uses IEEE 754 double-precision floating-point arithmetic, numeric outputs display up to 12 significant digits where applicable.
Always cross-check the displayed result against the scope note (The maximum logit is subtracted before exponentiation for stability. Probability_i = exp((x_i−max)/temperature) divided by their sum. Underflow can produce zero probabilities for distant logits; the values are not calibrated confidence estimates. Numeric output uses up to 12 significant digits; floating-point rounding can occur) before applying the value to production specifications, financial models, or lab records.
