^

x^y

Exponentiation. Use as any other arithmetic operator, like 5^(1/3). If exponent is an integer, you can use a negative base, otherwise you will get “NaN” with a negative base. If both arguments are integers, the result will be an integer.

---

abs

int/float abs(int/float x)

Absolute (positive) value of x.

---

arctan

float arctan(float x, float y)

Arctangent of x. Pass 1 as y (don’t ask…).

---

ceil

int ceil(float x)

Round x to the nearest integer that is not less than x.

---

cos

float cos(float x)

Cosine of x

---

div

div(x, y)

Unsigned integer division. Use as a division operator, like 3 + (20 div 5). If both dividend and divisor are integers, they will be treated as unsigned integers. If one of them is a float, div will perform the signed division just like vanilla division operator.

---

exponent

float exponent(float x)

E^X

---

floor2

sfall.h

int floor2(int/float value)

Works just like vanilla floor function, but returns correct integers for negative floats.

• NOTE: vanilla floor function works exactly the same as ceil for negative floats (i.e. basically trunc in C/C++).

---

log

float log(float x)

Natural logarithm of x.

---

round

int round(float x)

Round x to the nearest integer.

---

sin

float sin(float x)

Sine of x

---

sqrt

float sqrt(float x)

Square root of x.

---

tan

float tan(float x)

Tangent of x
