Hello Sir,
I am using ALTFP_LOG megafunction in my application,
so when i verify this ip core, i get abnormal results for
particular integer values.
If i give particular inputs of few numbers to ALTFP_LOG,
i was unable to get the accurate values to the given inputs.
For example, i'm using counter as input data block to generate some values
for the inputs of ALTFP_LOG megafunction,
or say that i'm using ALTFP_CONVERT to convert Integer-to-Float from the
counter due to input format of ALTFP_LOG megafunction.
and for the input values respected output values are given below..
x - ln(x)
1 - 0
2 to 4 - 1
5 to 12 - 2
13 to 33- 3
34 to 92- 4
so on...
but if we see the value of ln(92) = 4.5217885770490403096412170747265,
but here we see 4 as output..
as we check for the value for some hundred's or thousand's number,
the IP ALTFP_LOG megafunction output will not be correct.
So i would like to know how accurate this IP core is?
what i must do to get expected or accurate result..
Please kindly do the needful..
