# abseil-duration-factory-float

Checks for cases where the floating-point overloads of various `absl::Duration` factory functions are called when the more-efficient integer versions could be used instead.

This check will not suggest fixes for literals which contain fractional floating point values or non-literals. It will suggest removing superfluous casts.

Examples:

    // Original - Providing a floating-point literal.
    absl::Duration d = absl::Seconds(10.0);

    // Suggested - Use an integer instead.
    absl::Duration d = absl::Seconds(10);

    // Original - Explicitly casting to a floating-point type.
    absl::Duration d = absl::Seconds(static_cast<double>(10));

    // Suggested - Remove the explicit cast
    absl::Duration d = absl::Seconds(10);
