Return Value:
This function finds the normalized value of a Q16 value.
<libq.h>
_Q16 _Q16norm(_Q16 x);
x
ranges from -2147483648 to 2147483647.
This function returns the square root value of x in Q16 format. This
value ranges from 1073741824 to 2147483647 for a positive number
and -2147483648 to -1073741824 for a negative number.
This function finds the power result, given the base value x and the
power value y.
<libq.h>
_Q16 _Q16power(_Q16 x, _Q16 y);
x
ranges from 0 to 2147483647.
y
ranges from 0 to 2147483647.
This function returns the value of x to the power of y in Q16 format.
This value ranges from 0 to 2147483647.
This function generates pseudo random number with a period of
2147483648. This function uses the _Q16randomSeed variable as a
random seed value.
<libq.h>
_Q16 _Q16random(void);
None.
This function returns the generated random number in Q16 format. The
value of this output ranges from -2147483648 to 2147483647.
RndNum(n) = (RndNum(n-1) * RAN_MULT) + RAN_INC
SEED VALUE = 21845, RAN_MULT = 1664525, and RAN_INC =
1013904223.
This function returns the reciprocal of a Q16 value.
<libq.h>
_Q16 _Q16reciprocal(_Q16 x);
x
ranges from -2147483648 to 2147483647.
This function returns the reciprocal of x in Q16 format. The value of this
output ranges from -2147483648 to 2147483647.
