RealView® Developer Kit Compiler and Libraries Guide 6.2.3. Conversions between long longs and other number formats

The routines in Table 6.3 perform conversions between long longs and other number formats.

Table 6.3. Conversion routines involving long long format

Function	Argument type	Result type
`_ll_sto_f`	long long	float
`_ll_uto_f`	unsigned long long	float
`_ll_sto_d`	long long	double
`_ll_uto_d`	unsigned long long	double
`_ll_sfrom_f`	float	long long^[1]
`_ll_sfrom_f_r`	float	long long
`_ll_ufrom_f`	float	unsigned long long^a
`_ll_ufrom_f_r`	float	unsigned long long
`_ll_sfrom_d`	double	long long^a
`_ll_sfrom_d_r`	double	long long
`_ll_ufrom_d`	double	unsigned long long^a
`_ll_ufrom_d_r`	double	unsigned long long
^[1]Rounded toward zero, independently of the current rounding mode. This is because the C standard requires implicit conversions to integers to round this way, so it is convenient not to have to change the rounding mode to do so. Each function has a corresponding function with `_r` on the end of its name, that performs the same operation but rounds according to the current mode.
