Validates a floating point variable against a reference value.

VALIDATE_FP(actual, expected)
The floating point variable that will be checked
The floating point reference value

This macro is used to validate a single floating point value. Floating point values may have inaccuracies due to limitation in their precision. TestApe will call the function testape_validate_fp_accuracy() to obtain the required precision. The test can supply its own version of this function or rely on the default provided by the instrumenter. The default will return 0.00001f.

The macro can be used within tests or mocks. Parameter actual must be a floating point variable or an integer variable that can be cast to a floating point. Parameter expected can be a variable or a constant. The symbolic names of actual and expected are shown in the log. Proper chosen names for these can improve readability a lot.
