expm1 - Linux
Overview
expm1 calculates the exponential value of a floating-point number minus 1 with high accuracy. It is particularly useful in numerical computations and algorithms requiring precise exponential calculations.
Syntax
expm1(x)
where:
x
is the floating-point number to calculate the exponential value of minus 1.
Options/Flags
None.
Examples
-
To calculate the exponential value of 1.2 minus 1:
$ expm1(1.2) 2.3499291522431675
-
To use expm1 in a numerical computation:
distance = expm1(velocity * time) + initial_distance
Common Issues
None.
Integration
expm1 can be integrated with other numerical computation tools and libraries, such as:
- NumPy and SciPy: For advanced numerical calculations in Python.
