NAME
    sinh - returns hyperbolic sine of scalars and vectors.

SYNPOSIS
      float  sinh(float a);
      float1 sinh(float2 a);
      float2 sinh(float2 a);
      float3 sinh(float3 a);
      float4 sinh(float4 a);
 
      half   sinh(half a);
      half1  sinh(half2 a);
      half2  sinh(half2 a);
      half3  sinh(half3 a);
      half4  sinh(half4 a);
 
      fixed  sinh(fixed a);
      fixed1 sinh(fixed2 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.
