> # NAME

> sinh - returns hyperbolic sine of scalars and vectors.

> # SYNOPSIS

>       float  sinh( float  a );
>       float1 sinh( float1 a );
>       float2 sinh( float2 a );
>       float3 sinh( float3 a );
>       float4 sinh( float4 a );

>       half   sinh( half  a );
>       half1  sinh( half1 a );
>       half2  sinh( half2 a );
>       half3  sinh( half3 a );
>       half4  sinh( half4 a );

>       fixed  sinh( fixed  a );
>       fixed1 sinh( fixed1 a );
>       fixed2 sinh( fixed2 a );
>       fixed3 sinh( fixed3 a );
>       fixed4 sinh( fixed4 a );

> # PARAMETERS

> a

>   Vector or scalar of which to determine the hyperbolic sine.

> # DESCRIPTION

> Returns the hyperbolic sine of a.

> For vectors, the returned vector contains the hyperbolic sine of each element of the input vector.

> # REFERENCE IMPLEMENTATION

> sinh for a scalar float could be implemented like this.

>       float sinh(float x)
>       {
>         return 0.5 * (exp(x)-exp(-x));
>       }

> # PROFILE SUPPORT

> sinh is supported in all profiles except fp20.
