```{index} single: Test2::Compare::Float ``` # Test2::Compare::Float Compare two values as numbers with tolerance. ## DESCRIPTION This is used to compare two numbers. You can also check that two numbers are not the same. This is similar to Test2::Compare::Number, with extra checks to work around floating point representation issues. The optional 'tolerance' parameter controls how close the two numbers must be to be considered equal. Tolerance defaults to 1e-08. **Note**: This will fail if the received value is undefined. It must be a number. **Note**: This will fail if the comparison generates a non-numeric value warning (which will not be shown). This is because it must get a number. The warning is not shown as it will report to a useless line and filename. However, the test diagnostics show both values. ## SOURCE The source code repository for Test2-Suite can be found at `https://github.com/Test-More/test-more/`. ## MAINTAINERS - Chad Granum ## AUTHORS - Andrew Grangaard ## COPYRIGHT Copyright Chad Granum .
