C++ (Cpp) clamp24_from_float Examples

Example #1

File: primitives_tests.cpp Project: PDi-Communication-Systems-Inc/lollipop_system_media

inline void testClamp24(float f)
{
    int32_t ival = clamp24_from_float(f / (1 << 23));

    // test clamping
    ALOGV("clamp24_from_float(%f) = %d\n", f, ival);
    if (f > lim24pos) {
        EXPECT_EQ(ival, lim24pos);
    } else if (f < lim24neg) {
        EXPECT_EQ(ival, lim24neg);
    }

    // if in range, make sure round trip clamp and conversion is correct.
    if (f < lim24pos - 1. && f > lim24neg + 1.) {
        int ival2 = clamp24_from_float(float_from_q8_23(ival));
        int diff = abs(ival - ival2);
        EXPECT_LE(diff, 1);
    }
