function Rectangle::fixImprecision

Performs an imprecision check on the input value and fixes it if needed.

GD that uses C floats internally, whereas we at PHP level use C doubles. In some cases, we need to compensate imprecision.

float $input: The input value.

float $imprecision: The imprecision factor.

Return value

float A value, where imprecision is added to input if the delta part of the input is lower than the absolute imprecision.
