abs
The absolute value (or modulus) |x| of a real number x is the#NEWLINE#non-negative value of x without regard to its sign.#NEWLINE##SYNTAXHIGHLIGHT#Example: abs(-237.25)#NORMALTEXT##NEWLINE#
; Partly from http://en.wikipedia.org/wiki/Sign_function
sgn
The sign function or signum function is used to extract the sign of a number.#NEWLINE#Thus sgn(x) is 1 when x is positive, and sgn(x) is -1 when x is negative.#NEWLINE##SYNTAXHIGHLIGHT#Example: sgn(-23.94)#NORMALTEXT##NEWLINE#
; Partly from http://en.wikipedia.org/wiki/Rounding
round
Rounding a numerical value means replacing it by another value that is#NEWLINE#approximately equal but has a shorter, simpler, or more explicit#NEWLINE#representation. Amath rounds a number to the nearest integer.#NEWLINE#
; Partly from http://en.wikipedia.org/wiki/Rounding
trunc
Truncation is limiting the number of digits right of the decimal point,#NEWLINE#by discarding the least significant ones. Amath truncates a number to#NEWLINE#the nearest integer.#NEWLINE##SYNTAXHIGHLIGHT#Example: trunc(-23.94#NEWLINE#

sin
Sine is the trigonometric function that for an acute angle is the#NEWLINE#ratio between the leg opposite the angle when it is considered#NEWLINE#part of a right triangle and the hypotenuse.#NEWLINE#
; Partly from http://en.wikipedia.org/wiki/Trigonometric_functions
cos
Cosine is the trigonometric function that for an acute angle is the#NEWLINE#ratio between the leg adjacent to the angle when it is considered#NEWLINE#part of a right triangle and the hypotenuse#NEWLINE#
; Partly from http://en.wikipedia.org/wiki/Trigonometric_functions
tan
Tangent is one of the trigonometry functions. In a right triangle,#NEWLINE#the tangent of an angle is the opposite side over the adjacent side.#NEWLINE#
