MATHRandContext*

C Specification

#include <nitro/math/rand.h>
typedef struct { u64 x ; u64 mul ; u64 add ; } MATHRandContext32; typedef struct { u32 x ; u32 mul ; u32 add ; } MATHRandContext16;

Elements

x The current random number value. The MATH_Rand* function generates and assigns a value shifted from this number.
mul Stores the number that will be multiplied to get the next random number generated by the linear congruential method. The MATH_InitRand* function is initialized with unique constants, so if you change this value be sure to change this member afterward.
add Stores the number that will be added to get the next random number generated by the linear congruential method. The MATH_InitRand* function is initialized with unique constants, so if you change this value be sure to change this member afterward.

Description

The context structure of random number generated by linear congruential method.

MATHRandContext32 stores a 64-bit value and a 32-bit random number generated by MATH_Rand32. MATHRandContext16 stores a 32-bit value and a 16-bit random number generated by MATH_Rand16.
