Note<br />

Due to effectivity reason this function is implemented as inline<br />

<strong>and</strong> thus is not ANSI-C compliant.<br />

4.123.7 Re-entrancy<br />

The function is re-entrant.<br />

4.123.8 Code Example<br />

#include "mlib.h"<br />

tFrac32 f32In1, f32In2;<br />

tFrac32 f32Out;<br />

void main(void)<br />

{<br />

// input value 1 = 0.25<br />

f32In1 = FRAC32 (0.25);<br />

// input value 2 = 0.25<br />

f32In2 = FRAC32 (0.25);<br />

}<br />

// output should be FRAC32(0.5) = 0x40000000<br />

f32Out = MLIB_AddSat_F32(f32In1, f32In2);<br />

// output should be FRAC32(0.5) = 0x40000000<br />

f32Out = MLIB_AddSat (f32In1, f32In2, Define F32);<br />

// ##############################################################<br />

// Available only if 32-bit fractional implementation selected<br />

// as default<br />

// ##############################################################<br />

// output should be FRAC32(0.5) = 0x40000000<br />

f32Out = MLIB_AddSat (f32In1, f32In2);<br />

4.124 Function MLIB_AddSat_F16<br />

This function returns sum of two input parameters <strong>and</strong> saturate if necessary.<br />

4.124.1 Declaration<br />
