fix: Float functions should return the proper number of decimals

[mathieu-lemay]

Description

Fix the float functions to return the proper number of decimals, based off of the maxDecimals argument. Prior to this fix, a random value was generated between 0 and maxDecimals and that was used as the decimal portion. This meant that values generated with maxDecimals=2, the decimal portion of all generated values would be either .0, .1 or .2, instead of there being 2 digits in the decimal portion. With the fix, values generated with maxDecimals=2 will have a decimal portion anywhere between .00 and .99, inclusively.

Missing tests were also added for Float, Float32 and Float64
