Integer Built-In Functions

Click an item in the table below for details about that function.

`abs`	\|`x`\|
`abs_diff`	\|`x`-`y`\| without modulo overflow
`add_sat`	`x`+`y` and saturate result
`hadd`	(`x`+`y`) >> 1. The intermediate sum does not modulo overflow
`rhadd`	(`x`+`y`+1) >> 1. The intermediate sum does not modulo overflow.
`clamp`	`min`(`max`( `x`, `minval`), `maxval`)
`clz`	Number of leading 0-bits in `x`
`ctz`	Number of trailing 0-bits in `x`
`mad_hi`	`mul_hi`(`a`,`b`)+`c`
`mad24`	(Fast integer function.) Multiply 24-bit integer then add the 32-bit result to 32-bit integer
`mad_sat`	`a`*`b`+`c` and saturate the result
`max`	The greater of `x` or `y`
`min`	The lesser of `x` or `y`
`mul_hi`	High half of the product of `x` and `y`
`mul24`	(Fast integer function.) Multiply 24-bit integer values `a` and `b`
`rotate`	result[`indx`]=`v`[`indx`]<< `i`[`indx`]
`sub_sat`	`x` - `y` and saturate the result
`upsample`	`result`[i] = ((gentype)`hi`[i] << 8\|16\|32) \| `lo`[i]
`popcount`	Returns the number of non-zero bits in `x`.
