Declaration

inline int32_t floor_div(int64_t numerator, int32_t divisor)

Floor division for a positive divisor, matching the GTE's arithmetic shift.

Parameter	Type	Meaning
`numerator`	`int64_t`	Value supplied for numerator. Keep referenced or pointed-to data valid for the complete call.
`divisor`	`int32_t`	Value supplied for divisor. Keep referenced or pointed-to data valid for the complete call.

Returns: int32_t. Check the value before continuing when it represents success, availability or a resource handle.

Example

C++ example

#include "polygon.hpp"

// Assume these named values have been initialized with valid data:
// int64_t numerator
// int32_t divisor

auto result = epok::floor_div(numerator, divisor);

Why use it

It provides direct, allocation-conscious access to PSX polygon preparation, clipping and submission. No exception-based error path is implied by the signature.

Trade-offs and warnings

Call it only in the lifecycle phase described by the module. Validate indices, capacities and object state before use.

Declared in runtime/polygon.hpp:71
