Returns e (the base of natural logarithms) raised to a power.
Synopsis
`EXP(number)`
Arguments
 number An expression that resolves to a number within the following range: On a Windows system, if the value of number is greater than 335.601, a error occurs; if the value of number is less than -295.424, EXP returns zero (0).
Description
The EXP function takes the natural log constant e and raises it to the power specified by the number argument. The constant e (EXP(1)) is approximately 2.718282. If number is 0, the null string (""), or a non-numeric value, EXP parses number as 0 and returns 1.
The EXP function complements the action of the LN function and is sometimes referred to as the antilogarithm.
In Caché ObjectScript, the corresponding function is \$ZEXP.
Examples
The following example uses the EXP function to calculate e raised to the power of each of the integers -10 through 10:
```FOR x = -10 TO 10
PRINT "Natural log to the power of ",x," = ",EXP(x)
NEXT```
The following example uses the EXP function to return the hyperbolic sine of an angle:
```MyAngle = 1.3
