mpfr_float bertini::RandomMp	(	const mpfr_float &	a,
		const mpfr_float &	b )

create a random number in a given interval, at the current default precision

RandomMp() [3/4]

mpfr_float bertini::RandomMp	(	const mpfr_float &	a,
		const mpfr_float &	b,
		unsigned	num_digits )

create a random number in a given interval, at the specified precision

RandomMp() [4/4]

mpfr_float bertini::RandomMp

(

unsigned

num_digits

)

create a random number, at the specified precision

Parameters

num_digits

the precision that you desire.

RandomMpAssign()

void bertini::RandomMpAssign	(	mpfr_float &	a,
		unsigned	num_digits )

Set an existing mpfr_float to a random number, to a given precision.

This function is how to get random numbers at a precision different from the current default.
