Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

cast

Writing (type)value to force a conversion that might lose information.

An explicit conversion (cast) requests a conversion that may lose data or fail, such as (int)3.9, which truncates to 3.

Examples

(int)9.99 is 9: the cast chops the fraction off instead of rounding.
