Sig-Fig Calculator Tool - Texas Instruments TI-83 Plus Manual

Sig-Fig Calculator Tool

Calculations that involve measurements include a certain
amount of error. The precision of the measurement determines
which digits (known as significant digits or significant figures)
should be included when you report measurement results.
However, you will often encounter measurement values reported
with arbitrary precision. The Sig-Fig Calculator tool lets you:
• Display the significant figures of entered values.
• Perform mathematical operations using either decimal or
scientific notation and display the result with the correct
number of significant digits.
• Convert entries in decimal notation to scientific notation.
• Convert entries in scientific notation to decimal notation.
