Exp(-0.25) is the -0.25 power of E, and these scientific calculations can be easily performed by using FP calculator. As shown in the figure:

Perhaps it is because the exponential function 2.71828 based on natural logarithm is used too frequently in many occasions, such as in computer programming languages, so the first three letters of the English word "informative" are taken and an exp mark is made separately to avoid confusion with the letter variable E..

Exp, an exponential function based on natural constant E in advanced mathematics, is also a model airplane term, and its full name is exponent. In medical description, EXP refers to the term of use, that is, the expiration date.

In addition, EXP(Expedition) is one of the main products of Primavera, a world-famous American project management software supplier, and it is an internationally standardized construction management and contract and construction information management software.
