MATHRandContext*

Syntax

#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* functions get 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. This is initialized to a unique constant by the MATH_InitRand* functions, 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. This is initialized to a unique constant by the MATH_InitRand* functions, 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 internally stores a 64-bit value and the MATH_Rand32 function gets a 32-bit random number. MATHRandContext16 internally stores a 32-bit value and the MATH_Rand16 function gets a 16-bit random number.
