Quick guide
How to use this calculator
- Enter both decimal values.
- Read <, >, or = between them.
- Use the absolute difference for the size of the gap.
Calculation method
Align decimal scales before comparing
Both coefficients are expanded to the same power-of-ten scale. Integer comparison then determines the relation without rounding.
Worked example
Equivalent written decimals
Trailing zeros do not change a number's value.
1.20 = 1.2
Supported inputs
Precision and limits
Exact decimal input
Finite decimals use integer-scaled arithmetic, with no binary floating-point conversion.
Input boundary
Unless stated otherwise, use at most 200 digits total and 100 digits after the decimal marker.
