Mathematical Functions
From Flowcode Help
Jump to navigationJump to searchThe following mathematical functions can be used in calculations. Some are limited to different chip types.
Functions (Flowcode PIC only)
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 |

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 |
