Function Names
scientificDescription
This function converts a numeric value to a string where scientific notation is used all time. It is particularly useful to write them
into tables without losing accuracy, particularly for very small and very large magnitudes. 16 decimal digits are foreseen to ensure preserving
the full accuracy. The last 1-2 significan digits may deviate from the true value due to limited number of mantissa bit in the floating point numbers.
To read values in scientific notation format from tables, please refer to table configure() where reading scientific notation format must be enabled.
Vectorization: This function supports vectorization in the 1st function parameter.
Instead of providing a single value, you can provide a set or even a nested set which contain multiple values.
The function will then process every value and its return value contains a corresponding set containing all results.
Call as: function
Restrictions
Indirect parameter passing is disabled
