exp10

Computes the base 10 exponential of vector elements.

Syntax

Buffer API:

void exp10(queue& exec_queue, int64_t n, buffer<T,1>& a, buffer<T,1>& y, uint64_t mode = mode::not_defined, error_handler<T> errhandler = {} );

USM API:

event exp10(queue& exec_queue, int64_t n, T* a, T* y, vector_class<event>* depends, uint64_t mode = mode::not_defined, error_handler<T> errhandler = {} );

exp10 supports the following precisions and devices:

T Devices supported
float Host, CPU, and GPU
double Host, CPU, and GPU

Input Parameters

Buffer API:

exec_queue

The queue where the routine should be executed.

n

Specifies the number of elements to be calculated.

a

The buffer a containing input vector of size n.

mode

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.

errhandler

Sets local error handling mode for this function call. See the create_error_handler function for arguments and their descriptions. This is an optional parameter. The local error handler is disabled by default.

USM API:

exec_queue

The queue where the routine should be executed.

n

Specifies the number of elements to be calculated.

a

Pointer a to the input vector of size n.

depends

Vector of dependent events (to wait for input data to be ready).

mode

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.

errhandler

Sets local error handling mode for this function call. See the create_error_handler function for arguments and their descriptions. This is an optional parameter. The local error handler is disabled by default.

Output Parameters

Buffer API:

y

The buffer y containing the output vector of size n.

USM API:

y

Pointer y to the output vector of size n.

return value (event)

Function end event.
