# abseil-duration-conversion-cast¶

Checks for casts of absl::Duration conversion functions, and recommends the right conversion function instead.

Examples:

// Original - Cast from a double to an integer
absl::Duration d;
int i = static_cast<int>(absl::ToDoubleSeconds(d));

// Suggested - Use the integer conversion function directly.
int i = absl::ToInt64Seconds(d);

// Original - Cast from a double to an integer
absl::Duration d;
double x = static_cast<double>(absl::ToInt64Seconds(d));

// Suggested - Use the integer conversion function directly.
double x = absl::ToDoubleSeconds(d);


Note: In the second example, the suggested fix could yield a different result, as the conversion to integer could truncate. In practice, this is very rare, and you should use absl::Trunc to perform this operation explicitly instead.
