Quick guide

How to use this calculator

  1. Enter values using the notation shown beside each field.
  2. Choose a calculation mode when the tool offers more than one interpretation.
  3. Read the primary answer first, then inspect the supporting details.

Calculation method

Apply the stated definition

Convert a one-sided inequality to interval notation, or build a bounded interval from endpoints.

The calculator validates the mathematical domain before returning a result and does not replace undefined states with zero.

Worked example

Supported inputs

Precision and limits

Finite, bounded input

Numeric inputs use finite JavaScript floating-point values with magnitude limits. Results are normally displayed to 12 significant digits; outputs labelled approximate are not exact identities.

Notation

Enter ordinary finite decimals. Polynomial fields use coefficients in descending powers, separated by commas; for example 1, −3, 2 means x² − 3x + 2.
