vmax-element ( v -- n )

Vocabulary

math.vectors

Inputs

v	a sequence

Outputs

n

a real

Word description

Returns the maximum lane value, reducing lanes in order. Floating-point SIMD reductions select the number when only one operand is NaN, and select positive zero when comparing zeros of different signs.
