Test2::Compare::Float - Compare two values as numbers with tolerance.

NAME

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.
