Function Documentation

c3e_gamma()

c3e_number c3e_gamma

(

c3e_number

x

)

This function calculates the Gamma function of a number, which is a generalization of the factorial function. For positive integers, it returns the factorial of (x-1). For other values, it provides an approximation based on the Gamma function definition.

Parameters

x	The value for which the Gamma function is to be computed.

Returns

The Gamma function of the input value.

c3e_log_gamma()

c3e_number c3e_log_gamma

(

c3e_number

x

)

This function calculates the natural logarithm of the Gamma function for a given input. The log-Gamma function is useful in various statistical computations, especially in contexts where logarithmic scales are employed.

Parameters

x	The value for which the log-Gamma function is to be computed.

Returns

The natural logarithm of the Gamma function of the input value.

c3e_radian_degrees()

c3e_number c3e_radian_degrees

(

c3e_number

x

)

This function converts a given angle in radians to its equivalent in degrees.

Parameters

x	The angle in radians to be converted.

Returns

The equivalent angle in degrees.
