cexp2f - Linux
Overview
cexp2f is a command that calculates the base-2 exponential of a single-precision floating-point number. It is a part of the GNU Scientific Library (GSL) and is primarily used for performing exponential calculations efficiently in scientific and engineering applications.
Syntax
cexp2f(float x)
Parameters:
- x: The single-precision floating-point number for which the base-2 exponential is calculated.
Options/Flags
None.
Examples
Simple Exponential Calculation:
float result = cexp2f(5.0); // Calculates 2^5 = 32.0
Complex Exponential Expression:
float complex_result = cexp2f(x + I * y);
Common Issues
- NaN Result: If the input is NaN (Not-a-Number), the result will also be NaN.
- Inf Result: If the input is positive infinity, the result will be positive infinity. If the input is negative infinity, the result will be zero.
Integration
Combining with Other Math Functions:
float result = cexp2f(log2f(x)); // Calculates x
Using GSL Constants:
float result = cexp2f(GSL_LN2 * x); // Calculates 2^x
