Math Random Functions

float rand ()

Return value

Examples

forloop(int i = 0; 4) {
	printf("%s\n",typeinfo(rand()));
}
/*
result is:
float: 0.510393
float: 0.638238
float: 0.406844
float: 0.407974
*/

variable rand (variable from, variable to)

Arguments

• variable from - From value. Can be the following types:
  • int
  • float
  • double
  • vec3
  • vec4
  • dvec3
  • dvec4
  • ivec3
  • ivec4
• variable to - To value. Can be the following types:
  • int, long, float or double if the first argument is either int, float or double.
  • string if the first argument is int:
    • If a string is empty, it will equal to int(0).
    • If a string is nonempty, it will equal to int(1).
  • vec3 or dvec3 if the first argument is vec3
  • vec4 or dvec4 if the first argument is vec4
  • dvec3 if the first argument is dvec3
  • dvec4 if the first argument is dvec4
  • ivec3 if the first argument is ivec3
  • ivec4 if the first argument is ivec4

Return value

Examples

printf("%s\n",typeinfo(rand(-2,3)));
printf("%s\n",typeinfo(rand(-3.0,2)));
printf("%s\n",typeinfo(rand(vec3(-1,-2,-3),vec3(1,2,3))));
/*
result is:
int: 1
float: 1.5561
vec3: 0.19138 1.81164 -0.688218
*/

void srand (int seed)

Arguments

• int seed - Seed value for system random number generator.
