Detailed Description

Functions for converting to/from other types.

Function Documentation

df_denominator()

di_int df_denominator

(

df_frac

f

)

Get denominator as di_int.

Parameters

f

Fraction

Returns

Copy of denominator (caller must release)

Definition at line 1006 of file dynamic_fraction.h.

df_from_string()

df_frac df_from_string

(

const char *

str

)

Parse fraction from string.

Parameters

str	String to parse (format: "num/den" or "num")

Returns

New df_frac or NULL on parse error

Definition at line 954 of file dynamic_fraction.h.

df_numerator()

di_int df_numerator

(

df_frac

f

)

Get numerator as di_int.

Parameters

f

Fraction

Returns

Copy of numerator (caller must release)

Definition at line 1000 of file dynamic_fraction.h.

df_to_double()

double df_to_double

(

df_frac

f

)

Convert to double.

Parameters

f	Fraction to convert

Returns

Double approximation of the fraction

Definition at line 904 of file dynamic_fraction.h.

df_to_int64()

bool df_to_int64	(	df_frac	f,
		int64_t *	result
	)

Convert to int64_t if possible.

Parameters

f	Fraction to convert
result	Pointer to store result

Returns

true if conversion successful (f is integer and fits in int64_t)

Definition at line 914 of file dynamic_fraction.h.

df_to_string()

char * df_to_string

(

df_frac

f

)

Convert to string.

Parameters

f	Fraction to convert

Returns

Allocated string in format "num/den" or "num" if integer

Note

Caller must free the returned string
