# RandomReal

gives a pseudorandom real number in the range 0 to 1.

RandomReal[{xmin,xmax}]
gives a pseudorandom real number in the range xmin to xmax.

RandomReal[xmax]
gives a pseudorandom real number in the range 0 to xmax.

RandomReal[range,n]
gives a list of n pseudorandom reals.

RandomReal[range,{n1,n2,}]
gives an n1×n2× array of pseudorandom reals.

## Details and OptionsDetails and Options

• RandomReal[{xmin,xmax}] chooses reals with a uniform probability distribution in the range xmin to xmax.
• RandomReal[spec,WorkingPrecision->n] yields reals with n-digit precision. Leading or trailing digits in the generated number can turn out to be 0.
• RandomReal gives a different sequence of pseudorandom reals whenever you run the Wolfram Language. You can start with a particular seed using SeedRandom.
• A Method option to SeedRandom can be given to specify the pseudorandom generator used.
