REAL

Purpose:

Returns the Real component of a Complex expression.

REAL(val)

val

A scalar, series or table.

A scalar, series, or table.

real(42.1)

returns 42.1.

real(3.2 + 4.7i)

returns 3.2.

a = {1 + 10i, 2 + 20i, 3 + 30i, 4 + 40i};

b = real(a);

b == {1, 2, 3, 4}

b is a series that contains the real part of a.

REAL returns a real scalar or real series.

See IMAGINARY to return the imaginary part of a scalar or series as real values.

See CASTREAL to convert an input value to a real scalar value.
