Mathematical Functions
From Flowcode Help
Jump to navigationJump to searchThe 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 = 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 |
