sinpi
sinpi(x)
Compute $\sin(\pi x)$ more accurately than sin(pi*x), especially for large x.
Examples
In the Julia programming language, the function sinpi(x) computes the sine of πx more accurately than sin(pi*x), especially for large x.
julia> sinpi(0.5)
1.0
julia> sinpi(1)
0.0
julia> sinpi(2)
-2.4492935982947064e-16Here are some common examples of how to use the sinpi function:
-
Calculate sine of π/2:
julia> sinpi(0.5) 1.0This example computes the sine of π/2, which is equal to 1.
-
Calculate sine of π:
julia> sinpi(1) 0.0The
sinpi(1)evaluates to 0, as sin(π) is equal to 0. - Calculate sine of 2π:
julia> sinpi(2) -2.4492935982947064e-16The
sinpi(2)is a very small value close to 0, due to the floating-point precision limitations.
Please note that the sinpi function is particularly useful when dealing with large values of x as it provides more accurate results compared to sin(pi*x).
