Name Function
add void fl_add(const float_type *arg1,
const float_type *arg2, float_type *arg3);
Adds two floating-point numbers: (arg3 = arg1 + arg2).
sub void fl_sub(const float_type *arg1,
const float_type *arg2, float_type *arg3);
Subtracts two floating-point numbers: (arg3 = arg1 - arg2).
mul void fl_mul(const float_type *arg1,
const float_type *arg2, float_type *arg3);
Multiplies two floating-point numbers: (arg3 = arg1 *arg2).
div void fl_div(const float_type *arg1,
const float_type *arg2, float_type *arg3);
Divides two floating-point numbers: (arg3 = arg1 / arg2).
max void fl_max(const float_type *arg1,
const float_type *arg2, float_type *arg3);
Finds the max of two floating-point numbers: (arg3 = max(arg1, arg2)).
min void fl_min(const float_type *arg1,
const float_type *arg2, float_type *arg3);
Finds the minimum of two floating-point numbers: (arg3 = min(arg1,
arg2)).
Unary Arithmetic Operators
Table 22 lists the unary arithmetic operator functions.

Name Function
abs void fl_abs(const float_type *arg1, float_type *arg2);
Returns the absolute value of a floating-point number: (arg2 =
abs(arg1)).
neg void fl_neg(const float_type *arg1, float_type *arg2);
Returns the negative of a floating-point number: (arg2 = - arg1).
sqrt void fl_sqrt(const float_type *arg1, float_type *arg2);
Returns the square root of a floating-point number: (arg2 = √ arg1).
