sin off pi (3,14159) equal a 1,22465

[diazomar2004]

why sin off pi is equal a 1.22465  when is 0 the same ocurr with pi x2 6,283 is equal a 2,44 when is 0

i use sin example to control it

It sounds like the classic DEG/RAD issue, Maybe post your code to elaborate on this issue.

This is a display format issue.  You're looking at the number in scientific notation.  Right click the indicator -> Display Format and change to floating point.

thanks you

the precision of floating point numbers are limited. Pi and 2pi cannot be represented exactly as a floating point number, so sin(pi) and sin(2pi) can't be zero.

sin (pi) is something like sin(3,14159265358979311) and that's not zero.
