The 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:


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


Functions (Flowcode AVR only)

Flowcode includes an additional set of mathematical functions:


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

sinh( x ), cosh( x ), tanh( x ) - hyperbolic functions

isnan( x ), isinf( x ) - tests for not-a-number and infinity


Functions (Flowcode ARM only)

Flowcode includes an additional set of mathematical functions:


fabs( x ), floor( x ), ceil( x ) - absolute value, floor and ceiling functions

round( x ) - decimal rounding (x rounded to the nearest integer)

fround( x , y ) - floating point rounding (x rounded to y decimal places)

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
