4.173 Function MLIB_ShR_F32
This function shifts the first parameter to right by number defined by second parameter.
4.173.1 Declaration
tFrac32 MLIB_ShR_F32(register tFrac32 f32In1, register tU16 u16In2);
4.173.2 Arguments
Table 4-210. MLIB_ShR_F32 arguments
Type Name Direction Description
register tFrac32 f32In1 input First value to be right shift.
register tU16 u16In2 input The shift amount value.
4.173.3 Return
32-bit fractional value shifted right by the shift amount. The bits beyond the 32-bit
boundary of the result are discarded.
