**NAME**

mul24 - Fast integer function to multiply 24-bit integer values.gentypemul24(gentypex,gentypey);

**DESCRIPTION**

mul24multiplies two 24-bit integer valuesxandy.xandyare 32-bit integers but only the low 24-bits are used to perform the multiplication.mul24should only be used when values inxandyare in the range [-223, 223-1] ifxandyare signed integers and in the range [0, 224-1] ifxandyare unsigned integers. Ifxandyare not in this range, the multiplication result is implementation-defined.

**NOTES**

Fast integer functions can be used for optimizing performance of kernels. We use the generic type namegentypeto indicate that the function can takeint,int2,int3,int4,int8,int16,uint,uint2,uint3,uint4,uint8, oruint16as the type for the arguments.
