protected function CtoolsMathExpressionTestCase::assertFloat in Chaos Tool Suite (ctools) 7
A custom assertion with checks the values in a certain range.
Parameters
float $first: A value to check for equality.
float $second: A value to check for equality.
string $message: The message describing the correct behaviour, eg. "2/4 equals 1/2". The default message is used if this value is empty.
float $delta: The precision with which values must match. This accounts for rounding errors and imprecise representation errors in the floating point format. The value passed in should ideally be proportional to the values being compared.
string $group: Which group this assert belongs to.
Return value
bool TRUE if the assertion was correct (that is, $first == $second within the given limits), FALSE otherwise.
