Smallest floating point number
float-epsilon
The difference between 1.0 and the least value > 1.0 of a floating point number
float-precision

float-decimal-precision
Number of digits in mantissa base 10 of floating point number
float-maximum-exponent
Largest exponent in base radix of floating point number
float-minimum-exponent
Smallest exponent in base radix of floating point number
float-maximum-decimal-exponent
Largest exponent in base 10 of floating point number
float-minimum-decimal-exponent
Smallest exponent in base 10 of floating point number
maximum-double
Largest floating point number
minimum-double
Smallest floating point number
double-epsilon
The difference between 1.0 and the least value > 1.0 of a floating point number
double-precision
Number of digits in mantissa base radix of floating point number
double-decimal-precision
Number of digits in mantissa base 10 of floating point number
double-maximum-exponent
