Math Exponential Functions

List of functions:

variable exp(variable arg)

Returns e raised to the specified power.

Arguments

variable arg - Argument. Can be one of the following types:
- int
- long
- float
- double
- vec3
- vec4
- dvec3
- dvec4

Return value

e raised to the power of the argument. The type of returned value will depend on the argument type:

float for int, long, float arguments
double for double arguments
vec4 for vec4 arguments
dvec3 for dvec3 arguments
dvec4 for dvec4 arguments

variable log(variable arg)

Returns the natural logarithm of the argument.

Arguments

variable arg - Argument. Can be one of the following types:
- int
- long
- float
- double
- vec3
- vec4
- dvec3
- dvec4

Return value

Natural logarithm of the argument. The type of returned value will depend on the argument type:

float for int, long, float arguments
double for double arguments
vec4 for vec4 arguments
dvec3 for dvec3 arguments
dvec4 for dvec4 arguments

variable log10(variable arg)

Returns the base-10 logarithm of the argument.

Arguments

variable arg - Argument. Can be one of the following types:
- int
- long
- float
- double
- vec3
- vec4
- dvec3
- dvec4

Return value

Base-10 logarithm of the argument. The type of returned value will depend on the argument type:

float for int, long, float arguments
double for double arguments
vec4 for vec4 arguments
dvec3 for dvec3 arguments
dvec4 for dvec4 arguments

variable pow(variable base, variable exp)

Returns base raised to the power of exp (base^exp).

Arguments

variable base - Base. Can be one of the following types:
- int
- long
- float
- double
- vec3
- vec4
- dvec3
- dvec4
variable exp - Power. The value can be of the following types:
- int
- long
- float
- double
- vec3 if the first argument is vec3
- vec4 if the first argument is vec4
- dvec3 if the first argument is dvec3
- dvec4 if the first argument is dvec4

Return value

Base raised to the power of exp.

Examples

Source code (UnigineScript)

printf("%s\n",typeinfo(pow(2.0,2.0)));
printf("%s\n",typeinfo(pow(vec3(2.0,3.0,4.0),2.0)));
printf("%s\n",typeinfo(pow(vec3(2.0,3.0,4.0),vec3(2.0,3.0,4.0))));
/*
result is:
float: 4
vec3: 4 9 16
vec3: 4 27 256
*/

variable rsqrt(variable arg)

Inverted square root.

Arguments

variable arg - Argument. Can be one of the following types:
- int
- long
- float
- double
- vec3
- vec4
- dvec3
- dvec4

Return value

1.0 / sqrt(arg)
The type of returned value will depend on the argument type:

float for int, long, float arguments
double for double arguments
vec4 for vec4 arguments
dvec3 for dvec3 arguments
dvec4 for dvec4 arguments

variable sqrt(variable arg)

Square root.

Arguments

variable arg - Argument. Can be one of the following types:
- int
- long
- float
- double
- vec3
- vec4
- dvec3
- dvec4

Return value

Square root of arg. The type of returned value will depend on the argument type:

float for int, long, float arguments
double for double arguments
vec4 for vec4 arguments
dvec3 for dvec3 arguments
dvec4 for dvec4 arguments
