Name: sql sqrt floor |
298 |
| spl_sqrt_floor.c |
Algorithm:
Successive approximation of the equation (root + delta) ^ 2 = N
until delta < 1. If delta < 1 we have the integer part of SQRT (N).
Use delta = 2^i for i = 15 .. 0.
Output precision is 16 bits. Note for large input values (close to
0x7FFFFFFF), bit 15 (the highest bit of the low 16-bit half word)
contains the MSB information (a non-sign value). Do with caution
if you need to cast the output to int16_t type.
If the input value is negative, it returns 0.
