Hi, the code:
from Numeric import * def my_minimum(a): n=shape(a)[0] x = 1.0e20 for i in range(n): if a[i] < x: x = a[i] return x def strange(a): a[3] = -6303.0 h = my_minimum(a) for i in range(10): print i,a[i], a[i] = a[i] - h print a[i],h a = zeros(10,Float32) strange(a) b = zeros(10,Float64) strange(b) produces the output: 0 0.0 6303.0 -6303.0 1 0.0 6303.0 -6303.0 2 0.0 6303.0 -6303.0 3 -6303.0 0.0 0.0 4 0.0 0.0 0.0 5 0.0 0.0 0.0 6 0.0 0.0 0.0 7 0.0 0.0 0.0 8 0.0 0.0 0.0 9 0.0 0.0 0.0 0 0.0 6303.0 -6303.0 1 0.0 6303.0 -6303.0 2 0.0 6303.0 -6303.0 3 -6303.0 0.0 -6303.0 4 0.0 6303.0 -6303.0 5 0.0 6303.0 -6303.0 6 0.0 6303.0 -6303.0 7 0.0 6303.0 -6303.0 8 0.0 6303.0 -6303.0 9 0.0 6303.0 -6303.0 Can anybody tell me why in the Float32 version h is changed? Thank you in advance. Regards Rolf -- http://mail.python.org/mailman/listinfo/python-list
