EXP calculates the exponential function and returns e (the base of the
natural logarithm) to the power of numeric expression x.
EXP(x)
Usage Notes
■ EXP is calculated in single precision if the exponent x is an
integer or single-precision value. If you use any other numeric data
type, EXP is calculated in double-precision.
■ The exponent x must be less than or equal to 88.02969 when you are
using single-precision values and less than or equal to
709.782712893 when you are using double-precision values. If you use
a value of x that is not within those limits, BASIC produces the
error message, "Overflow."
■ The constant e is approximately equal to 2.718282.
