Owning Palette: Arithmetic & Comparison Express VIs

Use the Express Numeric functions to create and perform arithmetic and complex mathematical operations on numbers and to convert numbers from one data type to another. Use the VIs and functions on the Elementary & Special Functions palette to perform trigonometric and logarithmic functions.

Example

You also can access the following constants from this palette:

• positive infinity
• negative infinity
• machine epsilon

Palette Object	Description
Absolute Value	Returns the absolute value of the input.
Add	Computes the sum of the inputs.
Compound Arithmetic	Performs arithmetic on one or more numeric, array, cluster, or Boolean inputs. Select the operation (Add, Multiply, AND, OR, or XOR) by right-clicking the function and selecting Change Mode from the shortcut menu. When you select this function from the Numeric palette, the default mode is Add. When you select this function from the Boolean palette, the default mode is OR.
Decrement	Subtracts 1 from the input value.
Divide	Computes the quotient of the inputs.
Increment	Adds 1 to the input value.
Multiply	Returns the product of the inputs.
Negate	Negates the input value.
Numeric Constant	Use the numeric constant to pass a numeric value to the block diagram. Set this value by clicking inside the constant with the Operating tool and typing a value.
Random Number (0-1)	Produces a double-precision, floating-point number between 0 and 1. The number generated is greater than or equal to 0, but less than 1. The distribution is uniform.
Reciprocal	Divides 1 by the input value.
Round To Nearest	Rounds the input to the nearest integer.
Round Toward -Infinity	Truncates the input to the next lowest integer.
Round Toward +Infinity	Rounds the input to the next highest integer.
Scale By Power Of 2	Multiplies x by 2 raised to the power of n.
Sign	Returns the sign of number.
Square Root	Computes the square root of the input value.
Square	Computes the square of the input value.
Subtract	Computes the difference of the inputs.

Subpalette	Description
Math & Scientific Constants	Use the Math & Scientific Constants to create LabVIEW applications.
