iDevOS CALC "TAN" Command
Get the tangent of an angle.
Description
CALC( y, a, "TAN" ); // y = tan(a) = tangent of a CALC( y, a, b, "TAN" ); // y = tan(a) * b = tangent of a then multiplied by b
This command returns y
as the tangent of the angle a
. If the multiplier value b
is specified then the result is further multiplied by b
.
The angle y
by default is specified in Degrees. Angles used in trigonometric functions can be set globally to use Radians by the SYSTEM.angles
property.
Trigonometric functions: "COS"
, "SIN"
, "TAN"

Examples
Example 1
VAR(df, 0.0, FLT4); // result VAR(af, 15.0, FLT4); // angle VAR(bf, 5, FLT4); // multiplier CALC(df, af, "TAN"); // df = 0.2679 CALC(df, af, bf, "TAN"); // df = 1.3977
