I've noticed that Glibc prefers to use hex representation for float values, to
ensure an accurate representation. If you care to do so, here they are:
static float f32_numbers[] = {
-SNANF,
-NAN,
-INFINITY,
-FLT_MAX,
-0x1.1874b2p+103,
-0x1.c0bab6p+99,
-0x1.31f75p-40,
-0x1.505444p-66,
-FLT_MIN,
0.0,
FLT_MIN,
0x1p-25,
0x1.ffffe6p-25, /* min positive FP16 subnormal */
0x1.ff801ap-15, /* max subnormal FP16 */
0x1.00000cp-14, /* min positive normal FP16 */
1.0,
0x1.004p+0, /* smallest float after 1.0 FP16 */
2.0,
M_E, M_PI,
0x1.ffbep+15,
0x1.ffcp+15, /* max FP16 */
0x1.ffc2p+15,
0x1.ffbfp+16,
0x1.ffcp+16, /* max AFP */
0x1.ffc1p+16,
0x1.c0bab6p+99,
FLT_MAX,
INFINITY,
NAN,
SNANF
};
