How do greater-than and less-than work?
Comparison asks which number lies farther right on the number line—or whether both occupy the same point.
Use it to compare exact decimal values, thresholds, prices, measurements, and scores.
The key rule
What stays true
a > b means a lies to the right of b

1.20●1.2same location
Example
Apply it
1.20 = 1.2
Trailing zeros can change written precision but not a decimal's mathematical value.
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.
