Computes the square root of the input data.

template <typename T>
__aicore__ inline T sqrt(const T src)

**Table 1** Template parameters
Parameter	Description
T	Data type of the input data src. Currently, the supported data types are float and int64_t.

**Table 2** API parameters
Parameter	Input/Output	Description
src	Input	Source operand.

The input must be a non-negative number. If the input value is a negative number, the return value is meaningless.

Square root of the input data.

For data of the int64_t type, the calculation result is truncated to an integer.

int64_t src = 4;

int64_t result = AscendC::Std::sqrt(src); 
// result: 2
