Computes sin(X * pi) accurately.

📝 Syntax

• res = sinpi(x)

📥 Input argument

• x - a numeric value

📤 Output argument

• res - a numeric value

📄 Description

res = sinpi(x) computes sin(x * pi) accurately.

For odd integers, sinpi(x / 2) is +1 or -1.

For integers, sinpi(x) is exactly zero.

💡 Example

x = [0, 1/2, 1, 3/2, 2];
r = sin(x * pi)
res = sinpi(x)
