Screemer
I speak Streem, a prototype of a stream-based programming language. Screemer is a set of example programs in Streem programming language. a beginning of something that should end as a Streem documentation project.
The Examples
Run the examples with Docker to speak Streem.
git clone https://github.com/Stagyrite/speakingstreem.git
cd speakingstreem
docker build --tag 'speakingstreem' .
Math Library Documentation
Streem includes a wide range of mathematical functions, inspired by those available in the C standard library.
Constants
PI
Represents the mathematical constant Ο, accurate to the platformβs precision.
# Output: 3.1415926353898
print(PI)
E
Represents Eulerβs number, e, used in many exponential and logarithmic calculations.
# Output: 2.718281828459
print(E)
Number-Theoretic and Numeric Functions
ceil(x)
Returns the smallest integer not less than x.
# Output: 46
print(ceil(45.54))
fabs(x)
Returns the non-negative value of x.
# Output: 2
print(fabs(-2))
gcd(x, y)
Computes the largest whole number that divides both x and y. Inputs must be integers.
# Output: 2
print(gcd(4,10))
trunc(x)
Cuts off the decimal part of x, leaving just the integer component.
# Output: 9
print(trunc(9.13))
int(x)
Alias for trunc(x) β returns the integer part of a number.
floor(x)
Returns the greatest integer less than or equal to x.
# Output: 2
print(floor(2.7))
round(x)
Rounds x to the nearest integer.
# Output: 10
print(round(9.76))
frexp(x, y)
Breaks down x into a normalized fraction and an exponent. The exponent is stored in y.
# Output: 0.512500
print(frexp(16.4,5))
ldexp(x, y)
Calculates x * 2^y β effectively the inverse of frexp.
# Output: 6.00000
print(ldexp(6,3))
Trigonometric Functions
sin(x)
Returns the sine of x, where x is in radians.
cos(x)
Returns the cosine of x (radians).
tan(x)
Returns the tangent of x (radians).
asin(x)
Returns the angle whose sine is x.
acos(x)
Returns the angle whose cosine is x.
atan(x)
Returns the angle whose tangent is x.
hypot(x, y)
Calculates the length of the hypotenuse: sqrt(xΒ² + yΒ²).
# Output: 5
print(hypot(3,4))
Hyperbolic Functions
asinh(x)

log(x)
Computes the natural logarithm (base e) of x.
log2(x)
Computes the base-2 logarithm of x.
log10(x)

Power Functions
pow(x, y)
Returns the result of raising x to the power of y.
# Output: 25
print(pow(5,2))
sqrt(x)
Returns the square root of x.
# Output: 5
print(sqrt(25))
