Predefined Functions – sqrt
| Function name: | sqrt – Square Root |
| Synopsis: | sqrt(x) |
| Input data type | Output data type |
|---|---|
| real | real |
| complex | complex |
| quaternion | unsupported |
Description:
This function calculates the square root of the argument.
If the input type is real, then it calculates just the square root of real numbers! This means, sqrt(-4) = not defined (result is unpredictable).
If the input type is complex, then it calculates the square root of complex numbers! This means, sqrt(-4) = 2i.
