atan2

Computes the four quadrant arctangent of two numbers.

atanh

Inverse hyperbolic tangent function.

cbrt

Takes the cubic root of a number.

ceil

Returns the smallest integer greater than or equal to a number.

classify

Returns the floating point category of the number.

cos

Computes the cosine of a number (in radians).

cosh

Hyperbolic cosine function.

epsilon

Returns epsilon, a small positive value.

exp

Returns e^x, (the exponential function).

exp2

Returns 2^x.

exp_m1

Returns e^(self) - 1 in a way that is accurate even if the number is close to zero.

floor

Returns the largest integer less than or equal to a number.

fract

Returns the fractional part of a number.

hypot

Computes the length of the hypotenuse of a right-angle triangle given its legs’ lengths.

infinity

Returns the infinite value.

integer_decode

Returns the mantissa, base 2 exponent, and sign as integers, respectively.

is_finite

Returns true if this number is neither infinite nor NaN.

is_infinite

Returns true if this value is positive or negative infinity and false otherwise.

is_nan

Returns true if this value is NaN and false otherwise.

is_normal

Returns true if the number is neither zero, infinite, subnormal, or NaN.

is_sign_negative

Returns true if the input is negative.

is_sign_positive

Returns true if the input is positive.

ln

Returns the natural logarithm of the number.

ln_1p

Returns ln(1+n) (natural logarithm) more accurately than if the operations were performed separately.

log

Returns the logarithm of the number with respect to an arbitrary base.

log2

Returns the base 2 logarithm of the number.

log10

Returns the base 10 logarithm of the number.

max

Returns the maximum of the two numbers.

max_value

Returns the largest finite value that this type can represent.

min

Returns the minimum of the two numbers.

min_positive_value

Returns the smallest positive, normalized value that this type can represent.

min_value

round

Returns the nearest integer to a number. Rounds half-way cases away from 0.0.

signum

Returns a number that represents the sign of the input.

sin

Computes the sine of a number (in radians).

sin_cos

Simultaneously computes the sine and cosine of a number x. Returns (sin(x), cos(x)).

sinh

Hyperbolic sine function.

sqrt

tan

Computes the tangent of a number (in radians).

tanh

Hyperbolic tangent function.

to_degrees

Converts radians to degrees.

to_radians

Converts degrees to radians.

trunc

Returns the integer part of a number.
