54 of y. On platforms that support signed zeros, copysign(1.0, -0.0)

134 greatest common divisor of x and y
135
136 hypot(...)
137 hypot(x, y)
138

140
141 isclose(...)
142 isclose(a, b, *, rel_tol=1e-09, abs_tol=0.0) -> bool
143
144 Determine whether two floating point numbers are close in value.
145
146 rel_tol
147 maximum difference for being considered "close", relative to the
148 magnitude of the input values
149 abs_tol
150 maximum difference for being considered "close", regardless of the
151 magnitude of the input values
152

156 must be smaller than at least one of the tolerances.
157
158 -inf, inf and NaN behave similarly to the IEEE 754 Standard. That
159 is, NaN is not close to anything, even itself. inf and -inf are
160 only close to themselves.

207 Return the base 2 logarithm of x.
208
209 modf(...)
210 modf(x)
211
212 Return the fractional and integer parts of x. Both results carry the sign
213 of x and are floats.
214
215 pow(...)
216 pow(x, y)
217
