About Built-In Functions

Functions > About Built-In Functions

PTC Mathcad contains over 700 built-in functions. The built-in functions are denoted by a function name followed by one or more operands which are enclosed in parentheses. The operands of functions are called arguments, and each argument is specified by an expression. The result of a function is calculated by applying the operation of the function to the arguments. The built-in functions are grouped into the following categories:

Bessel	Fourier Transforms	Random Numbers
Complex Numbers	Graphing	Signal Processing
Conditional Branching	Hyperbolic	Solving
Curve Fitting	Image Processing	Special
Data Analysis	Interpolation and Prediction	Statistics
Design of Experiments	Log and Exponential	Strings
Differential Equation Solving	Monte Carlo Simulation	Trigonometric
Expression Type	Number Theory/Combinatorics	Truncation and Round-Off
File Access	Principal Component Analysis	Vector and Matrix
Finance	Probability Distribution	Wavelet

Additional Information

• The built-in function names are case-sensitive.

• To get help about a built-in function:

◦ Type or insert the function.

◦ Click the function name, not its argument placeholders, then press F1. The relevant help topic opens.

• All PTC Mathcad functions, built-in or user-defined, are limited to accepting a maximum of 16 arguments.

• Many common operations are represented by the appropriate mathematical notation, and so are considered operators, described separately.
