<sidebar>Sidebar: Editing Icon Properties</sidebar> The following mathematical functions can be used in calculations. All of these functions are now usable on each chip type.
Functions
Flowcode includes an additional set of mathematical functions:
| Function Prototype | Description |
|---|---|
| float = fadd(float, float) | Add two floating point numbers together |
| float = fsub(float, float) | Subtract two floating point numbers |
| float = fmul(float, float) | Multiply two floating point numbers |
| float = fdiv(float, float) | Divide two floating point numbers |
| float = fmod(float, float) | MOD function for floating point numbers |
| byte = isinf(float) | Checks to see if the floating point number is infinite |
| byte = isnan(float) | Checks to see if the floating point is not a number |
| byte = float_eq(float, float) | Compares two floating point numbers to see if they are equal |
| byte = float_ge(float, float) | Compares two floating point numbers to see if they are greater then or equal |
| byte = float_gt(float, float) | Compares two floating point numbers to see if they are greater then |
| byte = float_le(float, float) | Compares two floating point numbers to see if they are less then or equal |
| byte = float_lt(float, float) | Compares two floating point numbers to see if they are less then |
| int = random() | Generates a random number -32768 <=> 32767 |
| fabs( x ), floor( x ), ceil( x ) | Absolute value, floor and ceiling functions |
| fmod( x , y ) | Floating point modulus (remainder of x divided by y) |
| sqrt( x ), cbrt( x ) | Square and cube roots |
| log( x ), log10( x ) | Logarithms (base e and base 10) |
| exp( x ), pow( x , y ) | Exponential and power functions (x to the power of y) |
| sin( x ), cos( x ), tan( x ) | Trigonometric functions |
| asin( x ), acos( x ), atan( x ) | Inverse trigonometric functions |
| atan2( y , x ) | Four-quadrant inverse tangent |
