sin(+Number, -Result)

-Result is sin(+Number)

Evaluates the trigonometric function sin(Number) and unifies the resulting value with Result.
Number
A number.
Result
Output: float or breal.

Description

Evaluates the trigonometric function sin(Number) and unifies the resulting value with Result.

This predicate can be used as a function in arithmetic expressions. In coroutining mode, if Number is uninstantiated, the call to sin/2 is delayed until this variable is instantiated.

Modes and Determinism

Exceptions

(4) instantiation fault
Number is not instantiated (non-coroutining mode only).
(24) number expected
Number is not of a numeric type.

Examples

Success:
    Result is sin(1.5708).		% gives Result = 1.0
    Result is sin(-1.5708, Result).     % gives Result = -1.0
    Result is sin(0, Result).           % gives Result = 0.0
