Constants

Constants are used in formulas to specify fixed values. Example:

x = 

3 

* x + 

4

Here, 3 and 4 are constants. This topic explains how constants are used in Ultra Fractal formulas, 

and how Ultra Fractal determines the type of a constant (you should be aware of this).

Boolean constants are of type bool. There are only two boolean constants: true and false.

Integer constants are of type int. Integer constants are signed numbers within the range  

2147483648 .. 2147483647. Examples:

5

23

Floating point constants are of type float. They consist of a signed mantissa, optionally followed 

by the character E and a signed integer exponent to denote a power of ten. The exponent may range 

from  4931 to 4931. Examples:

3.0

1.23482

98.283E 3  

; 0.098283

1e5       

;  100000

Complex constants are of type complex. They consist of two floating point numbers, separated by 

a comma and surrounded by parentheses. Alternatively, you can specify an imaginary number by 

typing the letter i right behind a normal floating point number. Examples:

(

2

, 

3

)

(

3e2

, 

3.239

)  

; (300, 3.239)

2.3

i          

; (0, 2.3)

2 

+ 

1.63

i     

; (2, 1.63)

Color constants are of type color. They are created by supplying the 

rgb

, 

rgba

, 

hsl

, and 

hsla

functions with constant arguments. Examples:

rgb

(

0.5

, 

1

, 

0

)        

; orange

hsla

(

0

, 

0

, 

0.5

, 

0.5

)  

; transparent red
