Math Exponential Functions

Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

This class represents exponential functions.

Math Class

Members


variable exp ( variable arg ) #

Returns e raised to the specified power.

Arguments

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

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

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 (baseexp ).

Arguments

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

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

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
