lcm

#calc.lcm(96, 13)
floor
Rounds a number down to the nearest integer.
If the number is already an integer, it is returned unchanged.
Note that this function will always return an integer, and will
error if the resulting float or decimal is larger than the maximum
64-bit signed integer or smaller than the minimum for that type.
#calc.floor(500.1)
#assert(calc.floor(3) == 3)
#assert(calc.floor(3.14) == 3)
#assert(calc.floor(decimal("-3.14")) == -4)
ceil
Rounds a number up to the nearest integer.
If the number is already an integer, it is returned unchanged.
Note that this function will always return an integer, and will
error if the resulting float or decimal is larger than the maximum
64-bit signed integer or smaller than the minimum for that type.
#calc.ceil(500.1)
#assert(calc.ceil(3) == 3)
#assert(calc.ceil(3.14) == 4)
#assert(calc.ceil(decimal("-3.14")) == -3)
trunc
Returns the integer part of a number.
If the number is already an integer, it is returned unchanged.
Note that this function will always return an integer, and will
error if the resulting float or decimal is larger than the maximum
64-bit signed integer or smaller than the minimum for that type.
#calc.trunc(15.9)
#assert(calc.trunc(3) == 3)
#assert(calc.trunc(-3.7) == -3)

#assert(calc.fract(3) == 0)
#assert(calc.fract(decimal("234.23949211")) == decimal("0.23949211"))
round
Rounds a number to the nearest integer away from zero.
Optionally, a number of decimal places can be specified.
If the number of digits is negative, its absolute value will indicate the amount of significant integer digits to remove before the decimal point.
Note that this function will return the same type as the operand. That is,
applying round to a float will return a float, and to a decimal,
another decimal. You may explicitly convert the output of this function to
an integer with int, but note that such a conversion will error if the
float or decimal is larger than the maximum 64-bit signed integer or
smaller than the minimum integer.
In addition, this function can error if there is an attempt to round beyond
the maximum or minimum integer or decimal. If the number is a float,
such an attempt will cause float.inf or -float.inf to be returned
for maximum and minimum respectively.
#calc.round(3.1415, digits: 2)
#assert(calc.round(3) == 3)
#assert(calc.round(3.14) == 3)
#assert(calc.round(3.5) == 4.0)
#assert(calc.round(3333.45, digits: -2) == 3300.0)
#assert(calc.round(-48953.45, digits: -3) == -49000.0)
#assert(calc.round(3333, digits: -2) == 3300)
#assert(calc.round(-48953, digits: -3) == -49000)
#assert(calc.round(decimal("-6.5")) == decimal("-7"))
#assert(calc.round(decimal("7.123456789"), digits: 6) == decimal("7.123457"))
#assert(calc.round(decimal("3333.45"), digits: -2) == decimal("3300"))
#assert(calc.round(decimal("-48953.45"), digits: -3) == decimal("-49000"))
clamp

#calc.clamp(5, 0, 4)
#assert(calc.clamp(5, 0, 10) == 5)
#assert(calc.clamp(5, 6, 10) == 6)
#assert(calc.clamp(decimal("5.45"), 2, decimal("45.9")) == decimal("5.45"))

rem
Calculates the remainder of two numbers.
The value calc.rem(x, y) always has the same sign as x, and is smaller
in magnitude than y.
This can error if given a decimal input and the dividend is too small in
magnitude compared to the divisor.
#calc.rem(7, 3) \
#calc.rem(7, -3) \
#calc.rem(-7, 3) \
#calc.rem(-7, -3) \
#calc.rem(1.75, 0.5)
div-euclid
Performs euclidean division of two numbers.
The result of this computation is that of a division rounded to the integer
n such that the dividend is greater than or equal to n times the divisor.
#calc.div-euclid(7, 3) \
#calc.div-euclid(7, -3) \
#calc.div-euclid(-7, 3) \
#calc.div-euclid(-7, -3) \
#calc.div-euclid(1.75, 0.5) \
#calc.div-euclid(decimal("1.75"), decimal("0.5"))
rem-euclid
This calculates the least nonnegative remainder of a division.
Warning: Due to a floating point round-off error, the remainder may equal the absolute value of the divisor if the dividend is much smaller in magnitude than the divisor and the dividend is negative. This only applies for floating point inputs.
In addition, this can error if given a decimal input and the dividend is
too small in magnitude compared to the divisor.
#calc.rem-euclid(7, 3) \
#calc.rem-euclid(7, -3) \
#calc.rem-euclid(-7, 3) \
#calc.rem-euclid(-7, -3) \
#calc.rem-euclid(1.75, 0.5) \
#calc.rem-euclid(decimal("1.75"), decimal("0.5"))
quo
Calculates the quotient (floored division) of two numbers.
Note that this function will always return an integer, and will
error if the resulting float or decimal is larger than the maximum
64-bit signed integer or smaller than the minimum for that type.
$ "quo"(a, b) &= floor(a/b) \
"quo"(14, 5) &= #calc.quo(14, 5) \
"quo"(3.46, 0.5) &= #calc.quo(3.46, 0.5) $
norm
Calculates the p-norm of a sequence of values.
#calc.norm(1, 2, -3, 0.5) \
#calc.norm(p: 3, 1, 2)
