Parameters
Return value
A pair of values containing respectively the elementwise fractional and integral parts of x
, each having the type and sign of x
.
In particular:
x
is infinite {Nan, x}
is returned.x
is a Nan
{Nan, Nan}
is returned.For complex inputs the operation is applied to both real and imaginary parts.
The call pedantic(modf)(x)
ensures standard conformity : if x
is infinite, {0, x}
is returned.
