to the integer towards zero.

**mpf_urandomb**`(mpf_t`

¶`rop`, gmp_randstate_t`state`, mp_bitcnt_t`nbits`) -
Generate a uniformly distributed random float in

`rop`, such that*0 <=*, with`rop`< 1`nbits`significant bits in the mantissa or less if the precision of`rop`is smaller.The variable

`state`must be initialized by calling one of the`gmp_randinit`

functions (Random State Initialization) before invoking this function.

- Function:
`void`

**mpf_random2**`(mpf_t`

¶`rop`, mp_size_t`max_size`, mp_exp_t`exp`) Generate a random float of at most

`max_size`limbs, with long strings of zeros and ones in the binary representation. The exponent of the number is in the interval −`exp`to`exp`(in limbs). This function is useful for testing functions and algorithms, since these kind of random numbers have proven to be more likely to trigger corner-case bugs. Negative random numbers are generated when`max_size`is negative.
