Function MLIB_AbsSat_F32<br />

4.118.2 Arguments<br />

Table 4-155. MLIB_AbsSat_F32 arguments<br />

Type Name Direction Description<br />

register tFrac32 f32In input Input value.<br />

4.118.3 Return<br />

Absolute value of input parameter, saturated if necessary.<br />

4.118.4 Description<br />

This inline function returns the absolute value of input parameter. The input values as<br />

well as output value is considered as 32-bit fractional data type. The output saturation is<br />

implemented in this function, thus in case the absolute value of input parameter is outside<br />

the (-1, 1) interval, the output value is limited to the boundary value.<br />

The output of the function is defined by the following simple equation:<br />

Equation MLIB_AbsSat_Eq1<br />

Note<br />

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

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

4.118.5 Re-entrancy<br />

The function is re-entrant.<br />

4.118.6 Code Example<br />
