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.

Related Commands

  • exp: Calculates the natural exponential of a number.
  • log1p: Calculates the natural logarithm of 1 plus a number.
