**The Strength of First and Second Order Phase
Transitions from Partition Function Zeroes**

We present a numerical technique employing the density
of partition function zeroes (i) to distinguish between phase
transitions
of first and higher order, (ii) to examine the crossover between such
phase transitions and (iii) to measure the strength
of first and second order phase transitions in the form of latent heat
and critical exponents.
These techniques are demonstrated in applications to a number of models
for which zeroes are available.
