Computes a square root of sum of two squared elements.
Buffer API:
void hypot(queue& exec_queue, int64_t n, buffer<T,1>& a, buffer<T,1>& b, buffer<T,1>& y, uint64_t mode = mode::not_defined );
USM API:
event hypot(queue& exec_queue, int64_t n, T* a, T* b, T* y, vector_class<event>* depends, uint64_t mode = mode::not_defined );
hypot supports the following precisions and devices:
T | Devices supported |
---|---|
float | Host, CPU, and GPU |
double | Host, CPU, and GPU |
The function hypot(a,b) computes a square root of sum of two squared elements.
Argument 1 | Argument 2 | Result | Error Code |
---|---|---|---|
+0 | +0 | +0 | |
-0 | -0 | +0 | |
+∞ | any value | +∞ | |
any value | +∞ | +∞ | |
SNAN | any value | QNAN | INVALID |
any value | SNAN | QNAN | INVALID |
QNAN | any value | QNAN | |
any value | QNAN | QNAN |
Data Type | Threshold Limitations on Input Parameters |
---|---|
single precision | abs(a[i]) < sqrt(FLT_MAX) abs(b[i]) < sqrt(FLT_MAX) |
double precision | abs(a[i]) < sqrt(DBL_MAX) abs(b[i]) < sqrt(DBL_MAX) |
The hypot(a,b) function does not generate any errors.
Buffer API:
The queue where the routine should be executed.
Specifies the number of elements to be calculated.
The buffer a containing 1st input vector of size n.
The buffer b containing 2nd input vector of size n.
Overrides the global VM mode setting for this function call. See set_mode function for possible values and their description. This is an optional parameter. The default value is mode::not_defined.
USM API:
The queue where the routine should be executed.
Specifies the number of elements to be calculated.
Pointer a to the 1st input vector of size n.
Pointer b to the 2nd input vector of size n.
Vector of dependent events (to wait for input data to be ready).
Overrides the global VM mode setting for this function call. See the set_mode function for possible values and their description. This is an optional parameter. The default value is mode::not_defined.
Buffer API:
The buffer y containing the output vector of size n.
USM API:
Pointer y to the output vector of size n.
Function end event.
