Computes a signed fractional part for each vector element.
Buffer API:
void frac(queue& exec_queue, int64_t n, buffer<T,1>& a, buffer<T,1>& y, uint64_t mode = mode::not_defined );
USM API:
event frac(queue& exec_queue, int64_t n, T* a, T* y, vector_class<event>* depends, uint64_t mode = mode::not_defined );
frac supports the following precisions and devices:
T | Devices supported |
---|---|
float | Host, CPU, and GPU |
double | Host, CPU, and GPU |
The frac(a) function computes a signed fractional part for each vector element.
Argument | Result | Error Code |
---|---|---|
+0 | +0 | |
-0 | -0 | |
+∞ | +0 | |
-∞ | -0 | |
QNAN | QNAN | |
SNAN | QNAN |
The frac 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 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 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.
