Description

Mathematical Functions help us to evaulate the mathematical and trigonometrical functions of a given input number.

FunctionDescription
IntA Function, which returns the integer part of the given number
FixA Function, which returns the integer part of the given number
LogA Function, which returns the natural logarithm of the given number. Negative numbers disallowed
OctA Function, which returns the Octal value of the given percentage
HexA Function, which returns the Hexadecimal value of the given number
RndA Function, which returns a random number between 0 and 1
SgnA Function, which returns a number corresponding to the sign of the specified number
SqrA Function, which returns the square root of the given number. Negative numbers disallowed
AbsA Function, which returns the absolute value of the given number
ExpA Function, which returns the value of e raised to the specified number
SinA Function, which returns sine value of the given number
CosA Function, which returns cosine value of the given number
TanA Function, which returns tan value of the given number
