| <p>Evaluating this expression directly can lead to under- or overflows. This function performs the evaluation in a safe manner, making use of the following observations:</p> |
| <p>In order for the outcome of \( \exp(x) \) to be within the range of the minimum positive double-precision number (i.e., \( 2^{-1074} \)) and the maximum positive double-precision number (i.e., \( (1 + (1 - 2^{52})) * 2^{1023}) \), \( x \) has to be within the natural logarithm of these numbers, so roughly in between -744 and 709. However, \( 1 + \exp(x) \) will just evaluate to 1 if \( \exp(x) \) is less than the machine epsilon (i.e., \( 2^{-52} \)) or, equivalently, if \( x \) is less than the natural logarithm of that; i.e., in any case if \( x \) is less than -37. Note that taking the reciprocal of the largest double-precision number will not cause an underflow. Hence, no further checks are necessary. </p> |
