BFP - Big Floating Points

Library provides 256 byte floating point type and operations. Library provides:

• Floating point type.
• Initialization from double, float, long long, int and char* type.
• Convertion to string.
• Comparsion between BFP variables.
• Cyclometric functions
• Arthmetic operations.
• Exponential and logarithm operations.
• Inverse hyperbolic operations.
• Hyperbolic operations.
• Power operations.
• Round functions.
• Trygonometric operations.

Functions

Initialization

Initialization from these types are supported.

• BFP
• double
• float
• long long
• int
• char* (decimal notation)
• char* with given exponent (scientific notation)

For example

float value = 10;
bfp number1, number2, number3;
initString(&number1, "12.34567890");
initStringExp(&number2, "0.123", -1);
initFloat(&number3, value);

Arthmetic

• addition
• subtraction
• multiplication
• division
• factorial
• double factorial
• absolute value
• sign negation

For example

addBfp(&add1, &add2);
subBfp(&sub1, &sub2);
mulBfp(&mul1, &mul2);
divBfp(&div1, &div2);

Comparsion

• is equal
• is greather
• is lower
• is NaN
• is positive Inf
• is negative Inf
• is zero

For example

if(isNaN(value1))
{
    // Do something;
}

Conversion

• to char* in decimal notation
• to char* in scientific notation

For example

string1 = toString(&add1, 2);
string2 = toStringExp(&sub1, 2);

Cyclometric

• arc sine
• arc cosine
• arc tangent
• arc cotangent
• arc tangent with two parameters

For example

asinBfp(&asin);

Exponential and Logarithmic

• natural exponential function
• natural logarythm
• common logarythm

For example

expBfp(&exp);

Hyperbolic

• hyperbolic cosine
• hyperbolic sine
• hyperbolic tangent
• hyperbolic cotangent

For example

coshBfp(&cosh);

Inverse hyperbolic operations.

• inverse hyperbolic cosine
• inverse hyperbolic sine
• inverse hyperbolic tangent
• inverse hyperbolic cotangent

For example

acoshBfp(&acosh);

Power

• power
• square root

For example

powLongLong(&pow, 4);
sqrtBfp(&sqrt);

Round

• round
• ceil
• floor

For example

initString(&round, "2.3")
roundBfp(&round);

Trigonometry

• sine
• cosine
• tangent
• cotangent

For example

sinBfp(&sin);
cosBfp(&cos);
tanBfp(&tan);
ctanBfp(&ctan);
