Parameters
X—numeric value. The result must be in the range 10 -9999 through 10 9999 , which means that X must be in the range (approximately) -23,025.85 through +23,025.85.
Return Values
Exponential value of X.
If an error occurs, $procerror contains a negative value that identifies the exact error.
