<emph>Number:</emph> Any numeric expression that specifies the power that you want to raise "e" to (the base of natural logarithms). The power must be for both single-precision numbers less than or equal to 88.02969 and double-precision numbers less than or equal to 709.782712893, since $[officename] Basic returns an Overflow error for numbers exceeding these values.</paragraph>
