Computes the value of e raised to a specified power.

Input to this function.
**x**
must be in the range [-1, 1).

This input supports only scalar values of the fixed-point data type.

Computing exp(x) When x is Outside the Valid Range

Input Coercion

The CORDIC algorithm represents
**x**
internally as a fixed-point number with a 1-bit integer word length. The word length of
**x**
must be less than or equal to
64 bits, which means the fractional word length must be less than or equal to
63 bits. If you wire a value to
**x**
that has a fractional word length greater than
63 bits, this node rounds off the lower bits to achieve a fractional word length of
63 bits. For example, if you wire a fixed-point data type with a configuration of
I60<-5, 55>
to
**x**, this node coerces the configuration to be
I58<-5,53>.

If you wire a fixed-point data type to
**x**
with a fractional word length greater than
63 bits
and an integer word length less than
-62 bits, this node coerces the configuration to be
I1<-62, 63>
if the data type is signed. If the data type is unsigned, the coerced configuration is
U1<-62, 63>.

Boolean value that describes whether the next data element has arrived for processing. Wire the
**output valid**
output of an upstream node to this input to transfer data from the upstream node to this node.

True | The next data element has arrived for processing. |

False | The next data element has not arrived for processing. |

Boolean value that defines whether downstream nodes are ready for this node to return a new value. Use a
Feedback Node
to wire the
**ready for input**
output of a downstream node to this input of the current node.

True | Downstream nodes are ready for this node to return a new value. |

False | Downstream nodes are not ready for this node to return a new value. |

**Default:
**True

*e*
raised to the power of
**x**.

Boolean value that indicates whether this node computes a result that downstream nodes can use.

Wire this output to the
**input valid**
input of a downstream node to transfer data from the node to the downstream node.

True | Downstream nodes can use the result this node computes. |

False | This node returns an undefined value that downstream nodes cannot use. |
