Roberto Ierusalimschy cbe4998bc2 'math.random(n,m)' interval restricted in size, to avoid using conversion 
between 'double' and 'unsigned' (which can be slow and unreliable)
 2014-04-17 13:09:40 -03:00
Roberto Ierusalimschy 5336cc9d6a math.random: use 'random' when available + changes to work correctly 
for any integer interval (up to [minint,maxint])
 2014-04-10 14:53:33 -03:00
Roberto Ierusalimschy fdd137276b more precision for PI + no more RADIANS_PER_DEGREE +

Roberto Ierusalimschy 80cdf39d0e avoid using 'modf' in the implementation of 'math.modf', to avoid

'float*' is not compatible with 'double*'...)
